Halo Infinite 100% Collectibles Guide: Every Audio Log, Skull, Core, Armor Locker and Propaganda Tower

A complete field dossier for every tracked collectible across Zeta Halo, built for mission replay, open-world clean-up, lore recovery and 100 percent campaign completion.

This guide discusses Cortana’s final actions, the Weapon, Atriox, Escharum, the Harbinger, the Silent Auditorium, the Endless, the destruction of the UNSC Infinity, and the fate of several Spartan survivors. Read beyond the route instructions only when you are ready for the wider story.

You can replay completed campaign missions from the TACMAP. Mission Replay is the clean-up tool for Warship Gbraakon, Foundation, The Tower, Excavation Site, Conservatory, Spire, Nexus, Repository, House of Reckoning and Silent Auditorium. Your campaign progress, unlocked equipment upgrades, collected items and Skulls carry forward, so there is no reason to begin a new save simply because one mission collectible was missed.

Capture every Forward Operating Base before conducting a serious overworld sweep. FOBs reveal nearby Spartan Cores, Mjolnir Armor Lockers, UNSC distress calls and many other activities on the TACMAP. They also give you fast travel, vehicle delivery, weapon access and a dependable starting point after a failed mountain route.

Spartan Cores beep. Mjolnir Lockers emit a short electronic ping. Skulls burn with blue flame and make a distinct ambient sound. Propaganda Towers broadcast Glibnub’s speeches before they appear on the TACMAP. Use AI Scan near wrecks, sleeping bags, Forerunner ledges and Banished work sites, particularly when a map marker appears above or below your current elevation.

Do not treat Zeta Halo as a flat map. Most frustrating misses come from approaching a marker from the wrong vertical level. A collectible may be on a lower cliff shelf, inside a ravine, under a bridge, behind a Forerunner wall, or within a cave that has no obvious route from directly above.

Locations: Warship Gbraakon, Foundation, Outpost Tremonius.

Collectibles: 13 total, including 4 UNSC Audio Logs, 3 Banished Audio Logs, 3 Spartan Cores, 1 Mjolnir Armor Locker and 2 Skulls.

Story role: The campaign begins inside the wreckage of the UNSC defeat. Chief wakes after six months adrift, the Infinity is gone, the Banished control the ring, and the truth about Cortana is still deliberately incomplete.

Warship Gbraakon and Foundation are linear missions. Collect their Skulls before leaving each mission. Mission Replay makes clean-up possible, but collecting them during the first run preserves the rhythm of the opening campaign.

Location: Acquired automatically during the mission.

Lore file: Dr Halsey speaks from the final phase of the Created conflict. Cortana’s rule has become a galaxy-wide emergency, and the Infinity is preparing an operation built around a replacement AI designed to trap her.

Why it matters: Halo Infinite begins after the apparent conclusion of that operation, but this file establishes the hidden premise. The Weapon was never a new Cortana in the emotional sense. She was a precise containment tool, built to copy Cortana’s pattern, infiltrate the Domain-facing system, and lock her down long enough for the UNSC to act.

Location: Near the end of the Warship Gbraakon, on the upper bridge route before exiting the vessel.

Route: Once the main corridor opens toward the mission exit, search the bridge-side room rather than moving directly through the final door. The recording sits close to the command area.

Why it matters: Escharum frames the battle as a personal inheritance. Atriox’s apparent death has left him carrying the burden of the Banished war effort, but the log also exposes a leader whose rhetoric cannot hide grief. He is not simply a Brute commander seeking territory. He is trying to prove that the Banished can endure the loss of their greatest architect.

Location: After the first elevator sequence on the Warship Gbraakon.

Route: When the lift opens, stay in the immediate landing space before pushing into the next combat route. The field recorder sits among the broken UNSC equipment.

Why it matters: The Infinity does not fall as a clean military defeat. It becomes a scattering event. This record starts the survivor narrative that runs beneath the campaign, where crews, Marines and Spartans are not trying to win a war so much as stay alive long enough to become a problem for the Banished.

Effect: Explosion radius doubles.

Location: Freight-lift chamber near the beginning of Warship Gbraakon.

Route: In the two-storey hall with three freight lifts on the right, climb onto the central lift. The Skull is positioned above the cargo crate beside it. Grappleshot is not yet available, so use the lift structure and nearby boxes rather than trying to jump from the floor.

Location: Acquired automatically during Foundation.

Lore file: Halsey waits on Reach with Blue Team and asks the question that the campaign later forces Chief to confront: could John-117 truly kill Cortana if there were no other option?

Why it matters: It cuts through Halo Infinite’s apparent simplicity. Chief is not looking for a missing companion. He is walking through the consequences of a decision the UNSC expected him to make. The question gives later scenes with the Weapon their tension, because every new bond risks becoming a repetition of the old one.

Location: Late in Foundation, beside the Power Seed required to activate the elevator.

Route: Before carrying the final Power Seed to the elevator socket, turn to the equipment pile beside the seed. The recorder is close enough to be missed if you focus only on the objective icon.

Why it matters: This begins the account of Lucas Browning, a civilian technician pulled into the Banished excavation effort. His story gives the Harbinger a human-scale introduction. Long before the game names her motives, the player learns that ordinary people are being forced to open systems they do not understand.

Location: The room after the two-light-bridge encounter.

Route: Once the final light bridge opens, do not leave the chamber immediately. Search the side of the exit route near the Forerunner architecture.

Why it matters: Escharum’s obsession with the Cylixes makes clear that the Banished occupation is not solely a military operation. They are excavating history. The containers beneath Zeta Halo are not treasure chests, but prisons, archives and proof that the Forerunners buried something they feared.

Effect: Explosions accelerate objects farther and faster.

Location: In the chamber where a window reveals a blue energy orb and the direct route is blocked.

Route: Turn left instead of following the obvious blocked route. Grapple across the narrow Forerunner pillars, then climb toward the angular ceiling platform. The Skull rests on the upper structure, far above the intended combat floor.

Location: Exterior of Outpost Tremonius, beneath the Banished approach route.

Route: After reaching the surface, search the outer overhang and the path below the main landing platform before advancing into the larger open world.

Why it matters: The Banished logs are often blunt, but their bluntness is revealing. This is an army that celebrates endurance, hierarchy and conquest, yet remains driven by grief for Atriox and the memory of Brutes who died under Covenant rule.

Location: The landing-platform area at Outpost Tremonius.

Route: Search the right side of the landing zone after leaving the structure. The locker is not deep in the wilderness, but it is easy to ignore while heading toward the first FOB network.

Route: Treat Tremonius as your first Grappleshot-training ground. Search the upper landing pads, the lower repair path beneath the platform, and the wreckage to the east before pushing through the first Banished patrols. Each Core appears as a green UNSC hologram after you approach it, and all three provide early upgrades that make later mountain routes substantially easier.

Ringfall establishes Halo Infinite as a war story told after the war has already gone wrong. The Infinity is no longer a symbol of human recovery. It is wreckage. Halsey’s files turn the Weapon into a desperate contingency rather than a clean replacement for Cortana. Escharum’s records turn a broad enemy faction into a wounded army searching for proof that its suffering has meaning. The opening missions are small in physical scale, but the collectibles make them feel like the first recovered fragments of a catastrophe.

Locations: Recovery, The Tower, Ransom Keep, FOB Foxtrot and FOB Golf.

Collectibles: 37 total, including 12 UNSC Audio Logs, 3 Banished Audio Logs, 8 Spartan Cores, 5 Mjolnir Armor Lockers, 5 Propaganda Towers, 2 Forerunner Archives and 2 Skulls.

Story role: Chief begins turning scattered survival into organised resistance. The Banished response is immediate: prisoners, towers, fortified keeps and a campaign of intimidation designed to make the UNSC feel isolated.

Location: Ground-level container area to the right of the Tower entrance.

Route: Before beginning the main ascent, search the supply containers along the first courtyard. The log rests in the lower approach rather than on the tower itself.

Why it matters: Escharum does not treat the Harbinger as an ordinary asset. His language carries reverence and calculation. The alliance is not born from shared ideology. It is a compact between two forces that each believe the Forerunners left them a world worth taking.

Location: Second floor of the Tower, beside a pillar near Kinetic weapon ammunition.

Route: During the interior ascent, pause at the weapon cache rather than immediately climbing to the next level. The recorder sits against the support pillar.

Why it matters: Browning’s fear becomes more specific. He has seen the thing the Banished awakened. His account matters because the Harbinger’s first appearance is filtered through a civilian who has no language for Forerunner imprisonment, ancient species, or cosmic history. He only knows that something impossible was inside.

Effect: Rare combat dialogue becomes more common.

Location: At the top of the Tower.

Route: Once the main mission route reaches the upper roofline, climb to the highest external platform rather than dropping toward the objective. The Skull is hidden above the obvious end point. A Grappleshot chain is the safest approach.

Route: Collect one Core on the lower exterior approach before committing to the interior lift route. The second sits within the Tower’s upper combat structure. Use AI Scan after every elevator transition, because both can be passed while following the objective marker upward.

Location: North building inside Ransom Keep.

Route: Destroy the silos and complete the main objective. When the northern building opens, enter and turn left. The log rests on the floor just inside the newly accessible route.

Why it matters: This record treats the ring’s ancient systems as military infrastructure. That is a recurring Banished error. They are capable occupiers, but their confidence keeps colliding with systems designed by a civilisation that treated stars, species and time itself as engineering problems.

Location: South-east corner of the silo yard.

Route: Before leaving the yard, walk the barricade line along the south-east edge. The recording sits close to the outer defensive wall.

Why it matters: Atriox is absent for much of Halo Infinite, but his political weight never leaves the battlefield. The Banished do not see him as simply a commander. He is the proof that a Brute can reject Covenant hierarchy and build an army that answers to conquest rather than worship.

Home Defense: South-east of FOB Golf, at the cliff edge.

Touchdown: East of Boxer Squad, at a cliffside camp.

Perfect Aim: North-west of FOB Foxtrot, inside the ravine.

Overwatch: South-west of the Tower, at the westernmost lookout.

Buying Time: Starlight Squad’s camp, beneath the ramp near a mattress.

Intrepid Descent: On the summit above Starlight Squad, beside the fallen Elite general.

Archive route one: South of Ransom Keep, on the hill marked by giant stone-ring structures emerging from the ground.

Archive route two: On the eastern side of the region, at the summit of the largest mountain beside a Banished patrol. Use a Wasp if available, or climb the southern slope with repeated Grappleshot anchors.

Effect: Disables the HUD and weapon display.

Location: Southern mountain range, beyond Ransom Keep.

Route: Find the split between two mountain peaks on the southern edge of the playable area. Walk across the exposed hexagonal rock faces, then grapple to the lower right-hand outcrop. The Skull sits inside a narrow crack in the mountain. This is one of the campaign’s most easily missed Skulls because its marker does not appear until you are already close.

Remaining Lockdown count: 5 Mjolnir Armor Lockers, 8 Spartan Cores and 5 Propaganda Towers. Capture FOB Foxtrot and FOB Golf first, then work in a clockwise route through the Tower approaches, Ransom Keep, Starlight Squad, the southern mountain line and the eastern summit. The southern floating-island Propaganda Tower east of Starlight is the most commonly missed tower in the region.

Lockdown is where the Banished occupation becomes legible. Their power does not come from a single overwhelming battle. It is built from prisons, towers, silos, fortified roads, broadcasts and a willingness to exploit every fragment of UNSC weakness. The Spartan records counter that occupation with small acts of stubborn resistance. No grand counterattack is visible yet. There are only survivors making routes, defending camps and trying to remain connected long enough for someone to matter.

Locations: Excavation Site, Conservatory, Spire, Horn of Abolition, Forge of Teash, Armory of Reckoning, Redoubt of Sundering, FOB Alpha through Echo.

Collectibles: 86 total, including 27 UNSC Audio Logs, 9 Banished Audio Logs, 14 Spartan Cores, 14 Mjolnir Armor Lockers, 18 Propaganda Towers, 2 Forerunner Archives and 2 Skulls.

Story role: The campaign shifts from rescue and survival into a race over Banished excavation, Forerunner systems and the Harbinger’s release plan.

Connections is the largest early-game collection region. Do not try to clear it in one straight line. Capture FOB Alpha, Bravo, Charlie, Delta and Echo first. Then sweep the western cliffs, central Forerunner terrain, Excavation Site approaches and northern island routes in separate loops.

Location: Mining-laser platform at Excavation Site.

Route: Use the western grav lift to reach the elevated mining-laser room. In the first interior area, search the far corner beside Kinetic ammunition, Rocket Launcher supplies and Battle Rifle racks.

Why it matters: Browning finally describes the Harbinger’s reaction to freedom. Her calm frightens him more than rage would. The line matters because Halo Infinite’s ancient threat is never framed as a simple monster. She is conscious, patient and convinced that the Forerunners committed an unforgivable crime.

Location: Mining-laser control level.

Route: From the command console overlooking the excavation beam, turn away from the objective and search the rear viewing platform.

Why it matters: Escharum’s fixation on Master Chief is part military threat assessment and part mythology. To him, the Demon is the last surviving enemy worthy of an old warrior’s death. That belief becomes dangerous because it encourages Escharum to shape the entire campaign around spectacle rather than practical victory.

Location: Western approach road to Excavation Site.

Route: Look for the crashed UNSC truck and the line of tree trunks before reaching the main Banished perimeter. The recorder is at the improvised camp.

Why it matters: A small domestic phrase becomes painful on Zeta Halo. The Spartan Reverie had been a refuge, but survivors keep trying to reproduce that sense of shelter in places built from wreckage, ration packs and weapon crates.

Location: Eastern side of the Spire, near the destroyed Warthog.

Route: Before entering the deepest Forerunner route, walk the eastern exterior around the broken Warthog. The recorder sits beside the vehicle.

Why it matters: Browning’s story is about coercion. The Banished do not need him to understand what he is doing. They only need him frightened enough to continue. That makes his recordings a counterpoint to the Chief’s agency. One person acts because he chooses to. Another acts because every choice has been stripped away.

Route: Inside the central Spire, search beside the UNSC Audio Log rather than committing to the next objective. The Core is near the recovered resistance equipment, not high in the Forerunner structure itself.

Of Unrest and Unggoy: In the excavated interior corridor.

A Warning: In the upper building reached by the grav lift.

Operational note: Clear the Armory before collecting. The Banished records sit in spaces that are easier to search after the final enemy wave, especially the upper structure and the excavation passage.

A Boon: In an interior building within the fortress.

Our New Home: In the secondary structure after securing the prisoners.

Lore note: The Banished language of “home” is deliberately revealing. Zeta Halo is a conquest, but many Banished troops are also displaced survivors of the Covenant’s collapse. They are not seeking to restore the old order. They are claiming a future that they believe was denied to them.

RE: Damnable Eyes: In the main building after the entrance unlocks.

Secrets Below: Down the ramp inside the Banished silo.

Lore note: These records establish that the Banished excavation effort is not one coordinated certainty. Soldiers, engineers and commanders have competing interpretations of the ring. Fear appears beneath the bravado whenever the old systems begin behaving in ways the occupiers cannot control.

That Which Remains: Inside the main ammunition building.

Remain Vigilant: Behind the room opened after freeing captured Marines.

Route warning: Do not leave after taking the Redoubt. The second log only becomes accessible when the prisoner section opens, and a hammer-wielding Chieftain waits near the interior route.

Miscommunications: North-east of the Armory along the rocky path, beside a wrecked UNSC pod.

No Entry: North-east of the Armory, on top of a wrecked Warthog.

Nowhere to Hide: On the highest cliff south-east of the Horn, beside a sleeping bag.

They Are Listening: Outside the Horn, down the lower path beneath a tree and beside a pistol.

The Ally: On the rocky route between the cliff and Forge, inside the green-lit tunnel beside a sleeping bag.

Digging Deeper: On the hill south-east of the Forge at a small UNSC scouting post.

Escape Plan: At the end of the red-lit tunnel beside the Redoubt, on the rock platform.

Last-Ditch Effort: On the cliff north of the Redoubt, beside a rifle.

Enemy Territory: Behind the rock above the northern road junction east of FOB Echo.

The Calm Before: In the ravine north of the Bluebell and Indiana Squad routes.

Priority One: At Pyramid Squad’s elevated Banished-side camp.

Run and Guns: On the hex structures above the lake south-west of Forge of Teash.

Gravity: East of Balkarus, on top of a Forerunner hex structure.

Asunder: East of FOB Charlie, on the low cliff opposite the Propaganda Tower.

Alone: North-west of Thunder Squad, beside a crashed Pelican.

Breach Maneuver: West of the southern Beacon, on the south-facing cliff.

Effect: Disables the motion tracker.

Location: West of FOB Alpha.

Route: Follow the western cliff edge from FOB Alpha until you find a walkable rock outcrop. Move through the narrow opening and watch for a small doll on the ground. The Skull sits deeper inside the hidden cliff route.

Effect: Enemies throw and drop more grenades.

Location: Northern island route beyond Outpost Tremonius.

Route: Move through the Hunter canyon and search the tree-stump area marked by helmets and scattered Banished debris. The Skull is lower than the surrounding ridge line, so approach from the canyon rather than trying to land directly from above.

Mjolnir Armor Lockers: 14 total. Work from FOB Echo south toward the bridge overlook, then across the northern road bridge, waterfall line, Courier Squad hills, Lancer Squad camp, FOB Alpha cave, Spire cave, FOB Bravo ridge, FOB Delta cliff and Excavation Site forest.

Propaganda Towers: 18 total. The reliable sweep is south-west from Indiana Squad, north through Outpost Tremonius, east past Armory of Reckoning and Bengal Squad, then across the FOB Alpha, Bravo, Charlie, Delta and Echo boundaries.

Spartan Cores: 14 total. The hardest are below the hexagonal cliff edge near the Spire, inside the Banished turret pit with a grav lift, and beneath the mountain north of Jester Squad. Do not give up on a Core marker that seems to point at solid rock. It is usually indicating a cave route beneath the visible terrain.

Connections is the campaign’s clearest picture of Zeta Halo as an occupied country. The Banished are not merely defending combat arenas. They are building supply chains, prison systems, archaeology sites and cultural narratives. The UNSC logs answer with smaller stories of scouts, camps, improvised shelters and people trying to keep their comrades alive. Meanwhile, the Forerunner ruins refuse to become passive scenery. Every excavation record suggests the Banished are touching a history far larger than the war they think they are winning.

Locations: Pelican Down, the anti-air gun network, crashed UNSC hulls and the central island wreck fields.

Collectibles: 18 total, including 5 UNSC Audio Logs, 3 Banished Audio Logs, 5 Spartan Cores, 4 Propaganda Towers and 1 Mjolnir Armor Locker.

Story role: Graveyards is the physical evidence of the Infinity’s defeat. The landscape has become an archive of broken ships, emergency landings, failed defensive positions and scattered survivors.

Location: Central Pelican Down wreckage, inside the larger crashed UNSC hull.

Why it matters: The word retaliation is almost defiant here. The resistance does not have the strength for an invasion, but it still believes the Banished can be made to pay for every metre they occupy.

Location: South-east wreckage field, inside a fallen wing section.

Why it matters: Infinite keeps returning to this idea because it is the moral centre of the survivor logs. The campaign’s heroes move forward, but the records refuse to let the player forget those who did not.

Location: Just north of the eastern anti-air gun, inside a crashed Pelican.

Why it matters: The Banished are not presented as invincible. They are presented as relentless. That difference matters. The survivors can hurt them, but doing so demands a level of endurance that ordinary military doctrine was never designed to sustain.

Reformation: At the western anti-air site, inside the prefabricated building left of the lift.

Home: At the northern anti-air gun elevator base, in the left-hand prefabricated corner.

Loyalties: At the eastern anti-air gun, inside the prefabricated structure near the gun platform.

Location: Western anti-air gun area, along the outer edge of the main building.

Route: After destroying the anti-air gun, walk the exterior wall before boarding a vehicle toward the next objective. The locker is easiest to grab during the post-battle search.

Core one: East of the region, beside UNSC wreckage.

Core two: Western anti-air gun route, near the giant lift.

Core three: Northern anti-air site, at the mountain camp.

Core four: Inside the northern camp structure.

Core five: At the eastern anti-air gun, beyond the hill and lower cave line.

Graveyards strips the conflict of abstraction. The Infinity is no longer a name in a briefing or a distant flagship. It is metal in the mud, shattered troop carriers, scattered weapons and people recording messages because there may be nobody left to hear them in person. Escharum’s records sit uneasily beside that wreckage. His pursuit of legacy sounds grand until it is heard against the evidence of what grand ambitions do to ordinary soldiers.

Locations: Riven Gate, Annex Ridge, The Sequence, Beacon sites, Command Spire approaches, FOB Juliet through November.

Collectibles: 81 total, including 25 UNSC Audio Logs, 8 Banished Audio Logs, 15 Spartan Cores, 13 Mjolnir Armor Lockers, 13 Propaganda Towers, 3 Forerunner Archives and 4 Skulls.

Story role: The campaign reaches the part of Zeta Halo where Banished occupation, Forerunner infrastructure and the Harbinger’s plan become inseparable.

This is the hardest region to sweep without a Wasp. Several Lockers, Skulls and mountain-top Archives can be reached with a fully upgraded Grappleshot, but a Wasp removes the most frustrating vertical detours. Capture FOB Juliet, Kilo, Lima, Hotel and November before attempting the northern ridge and southern floating-structure routes.

Trench Warfare: East of Riven Gate. Climb the southern cliff beside the road to the sniper perch, where the log rests beside a rifle.

Convalescence: At the northern edge of Riven Gate. Grapple up from the grav-lift tunnel to the scout post on the upper ledge.

The Great Spine: Southern cliff-side building, inside the tunnel opened by the liberated route.

Encroaching Glory: Eastern gate compound. Activate the tower terminal, free the Marines, then search the back-right corner of the opened room.

A Hastily-Assembled Plan: North-east corner, beside the sniper rifle on the first level of the metal-spire formation.

Hitching a Ride: On the first level of the adjacent spire, closest to the Banished side of the compound.

Slow and Steady: In the central bunker route beside the grav lift.

Whispers From the Past: In the northern building after lifting the lockdown. Search the floor before leaving the compound.

Each Archaeological Findings log is located inside one of the four Forerunner Beacon structures activated during The Sequence. Collect the recording before leaving each Beacon chamber. The series turns Banished excavation into a mirror of Forerunner arrogance: powerful soldiers examining a civilisation they assume can be controlled, while repeatedly finding evidence that the civilisation’s deepest crimes were committed in the name of control.

Encroachment: South edge of FOB Lima, beside the perimeter tree line.

Drawing the Line: At the small lake near the top of the waterfall south-west of Riven Gate.

Red Tide: Northern end of the ravine east of Riven Gate. Drop down to the hidden lower ledge.

The Retreat: On the middle landmass between the Beacon routes, at the camp beside the foggy lake and waterfall.

Rubicon Protocol: On the mountain south of FOB Juliet.

What Lies Beneath: North-west of FOB Juliet, behind the destroyed vehicle.

Inquiries: East of the southern Beacon, on the cliff facing the map gap.

The Prize: North of FOB Hotel, beside ruined Pelican debris.

Uncharted: Along the road north-west of FOB Juliet, through the swamp.

Holding On: West of FOB Juliet, at the waterfall-base camp beside the hexagonal rock stub.

Infiltration: South-west of FOB Kilo, on the raised ground among hex columns.

The Assassin: On the road between the southern Beacon and FOB Kilo, against the mountain wall.

Killers: On the platform beside the eastern hex columns.

Message in a Bottle: On top of the tallest supported hex formation west of the northern Beacon.

Effect: Enemies have increased health.

Location: Command Spire.

Route: In the interior route where horizontal hex platforms pass through energy barriers, use the Forerunner-marked pieces to redirect toward the overhead opening. Grapple through the ceiling aperture and enter the side room beyond the doorway. The Skull is inside the upper chamber, far from the direct objective line.

Effect: Enemy weapons spawn with less ammunition.

Location: Eastern floating-island route near the Beacon network.

Route: Travel to the far eastern edge of the region. Locate the lone floating mountain beyond the main landmass and search the cliffside beneath the dead Elite. A Wasp makes the approach simple. Without one, use the nearest high ridge and chain Grappleshot swings across the broken terrain.

Effect: Shields recharge only after melee attacks.

Location: Waterfall cave beside the southern Beacon route.

Route: Stand at the base of the waterfall and look halfway up its right-hand face. Grapple into the small opening, crouch through the narrow passage and follow the red-lit cave to the Skull.

Effect: Promotes enemies to higher ranks.

Location: Northern mountain above the Beacon territory.

Route: Reach the northernmost mountain, then descend slightly to the isolated stone pillar below its summit. The Skull is on the pillar. Flying is safest, but a long Grappleshot climb from the upper ridge also works.

Archive five: High mountain north-east of FOB Juliet, beside abandoned Banished equipment.

Archive six: On the Banished-guarded island reached by following the river north-west of FOB Hotel.

Archive seven: North of FOB November, in the dip where the mountain routes join the older Ringfall landmass.

Mjolnir Armor Lockers: 13 total. Prioritise the bridge south of FOB November, the northern mountain beyond Riven Gate, the cliff edge south of FOB Kilo, the deep southern Wasp-only alcove, the ruined camp north of FOB Hotel and the mountain pass south-west of FOB Hotel.

Propaganda Towers: 13 total. The most commonly missed are the tower below the mountain west of the map boundary, the pair along the northern island edge, and the final tower south-west of FOB Hotel beneath the large Forerunner cliff.

Spartan Cores: 15 total. Search every mountain hollow, Beacon perimeter, crashed UNSC ship and Forerunner power structure. The core inside the mountain north of Riven Gate is especially easy to miss. Drop into the enormous earth split, clear the Banished force and find the crate beside the broken Forerunner structure.

Reformation is where Halo Infinite’s hidden narrative becomes a genuine archaeological thriller. The Banished are opening systems that the Forerunners did not merely abandon. They concealed them. The Spartan records keep the story grounded in human endurance, but the Beacon logs shift the scale outward. Every archive and excavation file suggests that the Forerunners feared the Endless because they represented a flaw in the old order: a people beyond the reach of the Halo Array, and therefore beyond the certainty that made the Forerunners feel entitled to rule.

Locations: Nexus, Repository, The Road and House of Reckoning.

Collectibles: 6 total, including 3 UNSC Audio Logs, 2 Banished Audio Logs and 1 Skull.

Story role: The campaign narrows into a confrontation with the Harbinger’s plan and Escharum’s chosen final battle.

Location: Nexus.

Route: Acquired automatically as the mission’s story progresses.

Why it matters: Halsey, Lasky and Palmer are no longer dealing in speculation. Their plan is explicit: use the Weapon to trap Cortana, then destroy the system before the Created can recover. The log reminds the player that the UNSC’s solution was desperate, ethically fraught and built around the same person Chief could not emotionally separate from his oldest friend.

Location: Nexus, after delivering the three Power Seeds.

Route: Once the three seed objective is complete, enter the first room leading toward the central seed mechanism. The recorder is set beside the route rather than at the core objective itself.

Why it matters: Browning has passed beyond fear into exhaustion. The recording does not expand ancient lore by itself. Its value is emotional. It shows the cost of being caught between forces that explain their cruelty as necessity.

Location: Repository.

Route: Acquired automatically during the mission.

Why it matters: The Weapon is described with cold technical language because that is how the UNSC had to think of her. A blank slate. A copy. A containment tool. The campaign’s emotional work lies in showing how quickly that language becomes inadequate once she begins making choices of her own.

Location: Repository, beside the Power Seed used to activate the elevator.

Route: Before carrying the final seed to the elevator socket, search beside the seed itself. The recorder is close to the critical path but easy to overlook in the urgency of the puzzle.

Why it matters: The title carries the full weight of the Prisoner series. Browning has been used, broken and discarded by powers who view individual lives as convenient tools. That is also the central moral accusation the Endless level at the Forerunners.

Effect: Grunt headshots trigger celebrations and confetti.

Location: Repository.

Route: After the terminal bridge sequence, return toward the door beside the terminal. A side route opens. Carry the Power Seed through the newly opened path. In the second hall, look up from the central angular platform and find the broken glass opening between Sentinel emitters. Climb through and defeat the Stealth Elites guarding the Skull.

Victory: House of Reckoning, outside Jega ‘Rdomnai’s room, on the table beside the large MA40 hologram.

Legacy: Escharum’s final room, at the rear left side of the chamber. Search before triggering the final confrontation.

Location: House of Reckoning, second reconstructed battlefield.

Route: In the second simulation arena, search the storage crates beside the raised central platform before progressing through the next encounter.

Reckoning closes the gap between personal grief and galactic consequence. Halsey’s recovered files explain how the Weapon came to exist. Browning’s final records show what it feels like to be reduced to a necessary sacrifice. Escharum’s last speeches reveal a warrior who has confused legacy with a death worth arranging. By the time the player reaches the House of Reckoning, every major force in the campaign has been shaped by the same dangerous idea: that individual lives can be spent for a future only the powerful get to define.

Location: Silent Auditorium.

Collectibles: 1 total, the Bandana Skull.

Story role: The final mission turns the campaign’s ancient mystery into an open wound. The Forerunners did not simply leave ruins here. They left evidence of imprisonment, fear and a history that has not finished happening.

Effect: Unlimited ammunition and grenades, with no equipment cooldown.

Critical condition: Do not kill any Sentinels during the mission before reaching the Skull.

Route: Near the end of Silent Auditorium, reach the statue-lined chamber and activate the light bridge. Cross it, then continue straight rather than turning toward the objective route on the left. The side door opens only if no Sentinels have been killed. The Skull waits inside.

The final Skull is mechanically playful, but its location is fitting. The Silent Auditorium is the place where Halo Infinite stops treating the Endless as a riddle box and frames them as a judgement on the Forerunners. The ancient civilisation built the Halo Array to preserve life from the Flood, yet its answer to a species beyond that system was confinement and erasure. The campaign does not explain every consequence. It establishes why the missing explanation matters.
