Halo Infinite collectibles by area

Halo Infinite Annex Ridge collectibles

Annex Ridge collectibles include 2 Banished Audio Logs, 1 Spartan Core, and 2 UNSC Audio Logs. Below, we’ll go through them in (roughly) the order you’ll encounter them while liberating the Annex Ridge Banished Outpost.

Annex Ridge UNSC Audio Log Outpost Intel 12

There’s only one road leading into Annex Ridge, so we’ll start there. As you approach from the east, head up onto the cliffs on the right (north) side. There’s a sniper position just past the main gate. You’ll find UNSC Audio Log Outpost Intel 12 there.

Annex Ridge Banished Audio Log Outpost Intel 11

Down in Annex Ridge’s excavation, there’s a tunnel that leads underground. Follow that tunnel to its end, and the Banished Audio Log Outpost Intel 11 is behind the grav lift back to the surface.

Annex Ridge UNSC Audio Log Outpost Intel 11

There are some low cliffs along the southeast corner of Annex Ridge. Climb them to find UNSC Audio Log Outpost Intel 11.

Annex Ridge Spartan Core

On your way to the fuel silo controls in the northwest of Annex Ridge, you’ll find this Spartan Core in a shed just to the left of the door into the control room.

Annex Ridge Banished Audio Log Outpost Intel 11

Over on the northwest side of Annex Ridge, you’ll find Banished Audio Log Outpost Intel 11 in the same room as the fuel silo controls.

Halo Infinite Excavation Site collectibles

Excavation Site collectibles include 1 Mjolnir Armor Locker, 1 Banished Audio Logs, 2 Spartan Cores, and 2 UNSC Audio Logs. Below, we’ll go through them in (roughly) the order you’ll encounter them while playing the Excavation Site mission.

Excavation Site Spartan Audio Log Reverie 01

Well before you reach the Excavation site — about 260m to the northwest — look for the branch in the road. You’ll find this Spartan Audio Log Reverie 01 near that intersection by a crashed truck.

Excavation Site Banished Audio Log Escharum’s Testimony 04

Once you take the grav lift up to the laser control room, Banished Audio Log Escharum’s Testimony 04 is directly opposite the laser controls.

Excavation Site UNSC Audio Log The Prisoner 03

On the west end of the Excavation Site control room, the UNSC Audio Log The Prisoner 03 is on the floor near a few UNSC weapons.

Excavation Site Mjolnir Armor Locker 1 of 1

Over in the southwest corner of the Excavation Site, you’ll find this Mjolnir Armor Locker next to a cliff. You’ll probably pass it on your way to the power pylons while disabling the laser.

Excavation Site Spartan Core 1 of 2

Not far from where you picked up the Mjolnir Armor Locker, look for the highest peak to the southeast overlooking the Excavation Site. It’s right against the excavation, so it’s hard to miss. Climb to the top to find this Spartan Core.

Excavation Site Spartan Core 2 of 2

The Excavation Site’s other Spartan Core is to the southeast. Look for the building (garage?) with a Ghost inside. This Spartan Core is on the second floor.

Halo Infinite Forge of Teash collectibles

Forge of Teash collectibles include 2 Banished Audio Logs, 1 Spartan Core, and 2 UNSC Audio Logs. Below, we’ll go through them in (roughly) the order you’ll encounter them while liberating the Forge of Teash.

Forge of Teash Banished Audio Log (1 of 2)

To the northeast of the Forge of Teash icon, there’s a Shade Turret you’ll have to deal with. Behind the turret, there’s a tunnel that leads back into the mountain. You’ll find this Banished Audio Log at the end of the tunnel.

Forge of Teash Spartan Core (1 of 1)

On the east side of the Forge of Teash, you’ll see a Spartan Core icon. This Spartan Core is on the second floor of the hangar there.

Forge of Teash Banished Audio Log (2 of 2)

In the same hangar where you pick up the Forge of Teash’s Spartan Core, the second Banished Audio Log is against a pillar on the ground floor.

Forge of Teash UNSC Audio Log (1 of 2)

Climb up to the mountain high above the Forge of Teash to the north. Look for a small (you’ll have to crouch) tunnel that’s lit up yellow. You’ll find this UNSC Audio Log inside.

Forge of Teash UNSC Audio Log (2 of 2)

Quite a way to the southeast of the Forge of Teash itself, there’s a small pile of UNSC gear up on the hill overlooking the road. You’ll find the second UNSC Audio Log there.

Halo Infinite Foundation collectibles

Foundation collectibles include 1 Banished Audio Log, 1 Skull, and 2 UNSC Audio Logs.

Foundation Skull 1 of 1 (Cowbell)

Fight your way through the crumbling Foundation until you pick up The Weapon in an exposition-filled cutscene. At the end of the long elevator ride, continue past the hallucination holograms into the next room. The Skull is high above you.

Use your scanner (down on the D-pad) to find it — it’s near the front of the room. You’ll have to get a little creative with your Grappleshot to reach this Skull, but it’s possible.

Foundation Banished Audio Log 1 of 1

Shortly after you grab the Cowbell Skull, you’ll have to fight your way across a couple light bridges. This Banished Audio Log is by the door leading out — you’ll walk right past it on your way to the exit.

UNSC Audio Log 1 of 2

You’ll receive the first of the two UNSC Audio Logs automatically during the “Foundation” main story mission.

UNSC Audio Log 2 of 2

Toward the end of the mission, you’ll need to collect a power seed to activate the elevator out (right before your fight with Tremonius). As you approach the power seed, this UNSC Audio Log is on the walkway on your left.

Halo Infinite House of Reckoning collectibles

Repository collectibles include 2 Banished Audio Logs and 1 UNSC Audio Log. Below, we’ll go through them in (roughly) the order you’ll encounter them during the House of Reckoning main story mission.

House of Reckoning UNSC Audio Log The Prisoner 07

In the first training room where you face several waves of Banished, the UNSC Audio Log The Prisoner 07 is to the right of the bunker in the center of the room, near the Warthog.

House of Reckoning Banished Audio Log Escharum’s Testimony 08

Continue through to the third training room — the one where you will probably get stuck. The Banished Audio Log Escharum’s Testimony 08 is leaning against the table with the holographic assault rifle as soon as you enter.

House of Reckoning Banished Audio Log Escharum’s Testimony 09

At the end of the level, you’ll find the pilot and Escharum. The Banished Audio Log Escharum’s Testimony 09 is behind where the pilot was being held. You can grab it before or after (or during, if you want to show off) your fight against Escharum.

Halo Infinite Nexus and Command Spire collectibles

Nexus and Command Spire collectibles include 2 UNSC Audio Logs and 1 Skull. Below, we’ll go through them in (roughly) the order you’ll encounter them during the Nexus and Command Spire main story missions.

Nexus UNSC Audio Log Recovered Files 03

You’ll collect UNSC Audio Log Recovered Files 03 automatically as part of the Nexus story mission. After your long ride on the elevator-shuttle-thing, you’ll eventually come to a long arena and a cutscene where you’ll pick up the Audio Log.

Nexus UNSC Audio Log The Prisoner 05

To continue from that room, you’ll need to collect a few power seeds. There are three corridors you’ll need to collect power seeds from — left, right, and center. As soon as you walk through the center door, turn to the left. UNSC Audio Log The Prisoner 05 is to the left of the weapons rack there.

Command Spire Mythic Skull

Once you leave the Nexus, you’ll ride a grav lift up to the Command Spire — which is where that mission begins. After a bit of fighting, you’ll teleport to an area where pieces of hexagon pillars (Ring alloy?) are being floated around. After some more fighting, you’ll grav lift up to where the pillars are being floated horizontally.

Follow the pillars forward to where they make a right turn. Grappleshot up above the pillars to find a ring-shaped walkway you can climb onto, and then climb up another level. There’s an open hallway there. Follow it to collect the Mythic Skull.

Halo Infinite Pelican Down collectibles

Pelican Down collectibles include 1 Mjolnir Armor Locker, 3 Banished Audio Logs, 5 Spartan Cores, and 5 UNSC Audio Logs. Below, we’ll go through them in (roughly) the order you’ll encounter them while playing the Pelican Down main story mission.

Pelican Down Spartan Audio Log Reverie 02

Starting at the center of the island (near the diamond-shaped mission marker on your map), look for the downed ship to the south. The back end of it is open. Climb inside, and the Spartan Audio Log Reverie 02 is on the floor along the right side.

Pelican Down Spartan Core 1 of 5

A little west of the main mission marker (and that Spartan Audio Log), there’s a chunk of debris with, effectively, a second floor. Use your Grappleshot to get up to it and grab this Spartan Core.

Pelican Down Spartan Audio Log Retaliation 01

Even farther to the southwest from the first Spartan Core, look for another chunk of debris resting against the cliff. The Spartan Audio Log Retaliation 01 is inside the wreckage on the ground.

Pelican Down Spartan Audio Log Retaliation 02

A little northwest of the Pelican Down mission marker on your map, there’s another crashed UNSC ship. This on has a gap in the side. Grapple up to it to find Spartan Audio Log Retaliation 02 in the corner.

Pelican Down Banished Audio Log Escharum’s Testimony 07

We’re heading to the Gun Battery in the east-northeast next. On your way up to the gun, you’ll pass a building on your right along a curve in the road. The Banished Audio Log Escharum’s Testimony 07 is inside.

Pelican Down Spartan Core 2 of 5

Just past the Gun Battery in the east, continue over the hill. There’s a tunnel in the rock there. Head inside to find this Spartan Core. (At the other end of the tunnel, you’ll find a Propaganda Tower and the next UNSC Audio Log.)

Pelican Down Spartan Audio Log Retaliation 03

Take the tunnel where you picked up Spartan Core 2 to its end — there’s a Propaganda Tower there. Turn around and climb up on top of the tunnel. Look for the crashed Pelican(s?). The Spartan Audio Log Retaliation 03 is inside along with a bunch of weapons.

Pelican Down Banished Audio Log Escharum’s Testimony 06

Head toward the northern Gun Battery. Before you take the elevator up, there’s a building to the left. The Banished Audio Log Escharum’s Testimony 06 is inside to the left.

Pelican Down Spartan Core 3 of 5

At the top of the elevator leading the northern Gun Battery, follow the road forward and then right (away from the gun). This Spartan Core is inside the building there.

Pelican Down Spartan Core 4 of 5

Take the road from the north Gun Battery and follow it southwest toward the southwestern Gun Battery. It’ll wind a bit and then turn north and run between two cliffs. This Spartan Core is above you on the right — there’s a Mongoose and weapons up there, too. There’s also a Propaganda Tower a little to the west.

Pelican Down Spartan Audio Log Retaliation 04

From Spartan Core 4, turn and climb up the mountain on the other side of the road (to the southwest). Near the top, you’ll find the Spartan Audio Log Retaliation 04 on a crate next to a sniper rifle.

Pelican Down Banished Audio Log Escharum’s Testimony 05

On your way to the western Gun Battery, the road will lead to the south and take a sharp turn north. You’ll have to climb through a building and cross a bridge (while dealing with a Shade Cannon). The Banished Audio Log Escharum’s Testimony 05 is on a table on the first floor of that building.

Pelican Down Mjolnir Armor Locker 1

Just across the bridge from that building, turn to the left. You’ll find this Mjolnir Armor Locker on the cliff above you.

Pelican Down Spartan Core 5 of 5

After you take down the western Gun Battery, you’ll ride the elevator back down to the crash site. At the bottom of the elevator, turn to the right (west). The last Spartan Core is with some weapons around the corner.

Halo Infinite Redoubt of Sundering collectibles

Redoubt of Sundering collectibles include 2 Banished Audio Logs, 1 Spartan Core, and 2 UNSC Audio Logs. Below, we’ll go through them in (roughly) the order you’ll encounter them while liberating the Redoubt of Sundering.

Redoubt of Sundering UNSC Audio Log Outpost Intel 07

On the northeast side of the Redoubt of Sundering, look for the gate inside. To the left of the gate, there’s a tunnel that leads to a back/side way in. You’ll find the UNSC Audio Log Outpost Intel 07 in the tunnel.

Redoubt of Sundering Spartan Core

Along the eastern wall of the Redoubt of Sundering — directly below where the tunnel with UNSC Audio Log 1 was located — you’ll find this Spartan Core next to a building.

Redoubt of Sundering Banished Audio Log Outpost Intel 08

In the southwest corner of corner of the Redoubt of Sundering, there’s an open building — there’s a plasma cannon out front and a brute carrying gravity hammer inside. You’ll find the Banished Audio Log Outpost Intel 08 leaning against a crate inside.

Redoubt of Sundering Banished Audio Log Outpost Intel 07

Right in the middle of the Redoubt of Sundering, there’s an open building with some guns and ammo crates inside. The Banished Audio Log Outpost Intel 07 is against a corner inside.

Redoubt of Sundering UNSC Audio Log Outpost Intel 08

Just outside of the walls on the north side of the Redoubt of Sundering, climb up onto the cliffs across the road. Near the sniper next (watchtower?), you’ll find this UNSC Audio Log Outpost Intel 08.

Halo Infinite Repository collectibles

Repository collectibles include 2 UNSC Audio Logs and 1 Skull. Below, we’ll go through them in (roughly) the order you’ll encounter them during the Nexus main story mission.

Repository Grunt Birthday Party Skull

Play through the Repository level until you come to the room with a hardlight bridge leading to a console, and doors to the right and left — like in the image above.

In this room, interact with the central console and watch the cutscene. Head back to the first platform and turn to the right. Use the wall to grappleshot across to the platform there. Head through the hallway and collect the power seed at the other end.

Take the power seed back to the main room, and cross the hardlight bridge to the far side. Turn to the left and grappleshot to the other platform. Take the hallway, and place the power seed in the receiver off to the right. This opens a room a bit later in the Repository.

Return to the hardlight bridge and continue with the mission. Before long, the Weapon will direct your attention to a window. After that, push through two more rooms.

In the third room, the Grunt Birthday Party Skull is above you and directly ahead. Be careful climbing up, though, because this Skull is guarded by four cloaked Elites.

Repository UNSC Audio Log Recovered Files 04

You’ll receive UNSC Audio Log automatically later in the mission shortly after you activate the second grav lift and then survive the lockdown.

Repository UNSC Audio Log The Prisoner 06

In the same room where you see the notification about Recovered Files 04, UNSC Audio Log The Prisoner 06 is on a console next to a hologram of Halo Zeta.

Halo Infinite Riven Gate collectibles

Riven Gate collectibles include 2 Banished Audio Logs, 1 Spartan Core, and 2 UNSC Audio Logs. Below, we’ll go through them in (roughly) the order you’ll encounter them while liberating the Riven Gate Banished Outpost.

Riven Gate UNSC Audio Log Outpost Intel 13

As you approach the Riven Gate from the west, climb up onto the cliffs to the left (north) of the outpost. About even with the first sniper tower, you’ll find UNSC Audio Log Outpost Intel 13 on the rocks there.

Riven Gate Banished Audio Log Outpost Intel 13

Continue along the northern wall of the cliffs to the building where the main gate controls are. The Banished Audio Log Outpost Intel 13 is to the right of the controls.

Riven Gate Banished Audio Log Outpost Intel 14

Directly across (to the south) of that Banished Audio Log Outpost Intel 13, there’s another large building with the generator controls inside. At the back of the building, right at the entrance to the tunnel, you’ll find the Banished Audio Log Outpost Intel 14.

Riven Gate Spartan Core

From Banished Audio Log Outpost Intel 14, continue through the tunnel and back to the west. Still inside the building, you’ll see this Spartan Core in an alcove ahead of you.

Riven Gate Mjolnir Armor Locker

High above Riven Gate on the southern cliffs, you’ll find this Mjolnir Armor Locker by the road that runs along the the cliff. (In the image above, Riven Gate is ahead and to the right.)

Riven Gate UNSC Audio Log Outpost Intel 14

Continue east along the southern cliffs of Riven Gate past the eastern gate. You’ll find the UNSC Audio Log Outpost Intel 14 on a peak overlooking that gate.

Halo Infinite The Sequence collectibles

Sequence collectibles include 4 Banished Audio Logs, 4 Mjolnir Armor Lockers, 5 Spartan Cores, and 1 Skull. Below, we’ll go through them in (roughly) the order you’ll encounter during The Sequence main story mission.

The Sequence west Beacon Banished Audio Log Archaeological Findings 04

The Banished Audio Log Archaeological Findings 04 is in the west (southwest, really) Beacon you’ll need to visit during The Sequence main story mission.

The Sequence west Beacon Spartan Core

Facing the front of the westmost Beacon, this Spartan Core is a little way off to the right near an overturned Warthog.

The Sequence west Beacon Mjolnir Armor Locker

While you’re here, there’s a Mjolnir Armor Locker high on a ridge about 275m north-northwest of the western Beacon. The locker is on the north side of the ridge, just below the peak. (There’s also a Propaganda Tower on the other side of the road.)

The Sequence north Beacon Mjolnir Armor Locker

On your way to the northern Beacon, check the ridge just north of FOB Juliet to find this Mjolnir Armor Locker.

The Sequence north Beacon Spartan Core 1

As you approach the north Beacon from the south (probably from FOB Juliet), look to the right (east). There’s a cave in the cliff there with some Banished forces inside. Clear them out and grab this Spartan Core.

The Sequence north Beacon Spartan Core 2

At the northern Beacon itself, look up at the balcony level above the door. This Spartan Core is up there with some weapons.

The Sequence north Beacon Banished Audio Log Archaeological Findings 01

Inside the north Beacon, you’ll find the Banished Audio Log Archaeological Findings 01 at the bottom of the first ramp.

The Sequence south Beacon Spartan Core

When you finally fight your way to the southern Beacon, head around to the back to find this Spartan Core.

The Sequence south Beacon Banished Audio Log Archaeological Findings 03

In the tunnel below the southern Beacon, you’ll find Banished Audio Log Archaeological Findings 03 next to a dead Brute.

The Sequence south Beacon Mjolnir Armor Locker

As you approach the southern Beacon, look for a spire of rock(?) to the right (south). You’ll need to use your Grappleshot to climb up and open this Mjolnir Armor Locker.

The Sequence east Beacon Mjolnir Armor Locker

There is another Mjolnir Armor Locker under the long bridge that leads toward the eastern Beacon.

The Sequence east Beacon Spartan Core

You’ll find a Spartan Core at the east end of the long bridge leading to the east Beacon.

The Sequence east Beacon Banished Audio Log Archaeological Findings 02

Banished Audio Log Archaeological Findings 02 is in the tunnel beneath the eastern Beacon.

Black Eye Skull

While it’s not near any of the four Beacons, you will be in the right area to pick up the Black Eye Skull during The Sequence.

On the southern island (Reformation), there’s a waterfall along the south side of the road about halfway between FOB Juliet and Riven Gate Banished Outpost. There’s a hidden tunnel about halfway up the waterfall on the right side.

You can’t see the tunnel from the outside, so it’ll take a few tries to find it. Grappleshot up, and crouch to pass through the tunnel. The Black Eye Skull is in a cave at the other end.

Halo Infinite Spire collectibles

Spire collectibles only include 1 UNSC Audio Log — and you’ll find that before you head up into the Spire. We’re also going to include a nearby Spartan Core — it’s not part of the Spire collectibles, but it’s right there, so we’ll point it out.

Spire (nearby) Spartan Core

As you approach the Spire, look to the west. There is a Spartan Core there near the wreckage of a downed Pelican.

Spire UNSC Audio Log The Prisoner 04

Just a little north of that Spartan Core, there’s a destroyed Warthog. The UNSC Audio Log The Prisoner 04 is on the ground next to that Warthog. (It’s unclear why this one counts as part of Spire, but the Spartan Core doesn’t.)

Halo Infinite Tower collectibles

The Tower collectibles include 1 Mjolnir Armor Locker, 1 Banished Audio Log, 2 Spartan Cores, 1 Skull, and 1 UNSC Audio Log. Below, we’ll go through them in (roughly) the order you’ll encounter them while playing the main story mission “The Tower.” We start on the ground and move up, floor-by-floor.

Tower Banished Audio Log 1 of 1

Disable the hardlight door to enter The Tower, and walk through the corridor with two Grunts inside. That hallway ends at The Tower’s interior courtyard.

When stand at the hallway’s exit (or the courtyard’s entrance, if you prefer), the Banished Audio Log is inside the first structure directly ahead of you. (You can see the courtyard entrance door just above the part that says 36 on the AR in the image above.) Listen for the telltale beeping, if you’re having trouble locating it.

Tower Spartan Core 1 of 2

The first Spartan Core in the Tower is on the ground near the grav lift — it’ll be easier to find it once the area is cleared out and the grav lift is active. Stand facing the grav lift, and look to the right. There’s an open container there with some guns and ammo inside. Cut through there and into the container to its left to find this Spartan Core.

Tower Mjolnir Armory 1 of 1

Before you ride the grav lift up, stay on the ground. Facing the grav lift, turn left. Head over the the edge of the cliff there, and look underneath the platforms on your right to find this armor locker.

Tower UNSC Audio Log 1 of 1

After you activate the grav lift and ride it into the Tower, you’ll pick up the Threat Sensor. Continue up to the second floor, and take a left. Continue around the corner a bit, and keep pinging your AI Scan (down on the D-pad). The UNSC Audio Log will be behind a column on your right.

Tower Spartan Core 2 of 2

On the third floor up, take a left. You’ll run into a (shielded) Brute and an Elite. Watch for this Spartan Core on your right (once they’re dead).

Tower Skull (I Would Have Been Your Daddy / IWHBYD)

It’s easiest to come back for the Tower’s collectible Skull later in the game when you have access to a Wasp — which means you’ll have to wait until you’ve unlocked it at a FOB before you can reach it. It’s also possible to grab it with an upgraded Grappleshot, but it’ll take a little practice. No matter how you get there, the collectible is sitting on a crate on the platform on the roof of The Tower.

The video above shows how we got this Skull with the Grappleshot. You’ll need to upgrade it to the second level, Quickshot. Climb the Tower from the outside along one of the supports. At the top, Grappleshot onto the platform away from the Tower, and hold the left thumbstick to the side to adjust your flight. At the top of your arc, Grappleshot back to the platform and grab the Skull.

Halo Infinite Warship Gbraakon collectibles

Warship Gbraakon collectibles include 1 Banished Audio Logs, 2 UNSC Audio Log, and 1 Skull. Below, we’ll go through them in (roughly) the order you’ll encounter them during the Warship Gbraakon main story mission.

Warship Gbraakon UNSC Audio Log Recovered Files 01

You’ll receive the UNSC Audio Log Recovered Files 01 automatically at the beginning of the mission.

Warship Gbraakon Spartan Audio Log Evacuation 01

Play through the mission until you ride your first elevator up (it’ll take a few minutes to get there). At the top of the elevator, the Spartan Audio Log Evacuation 01 is directly ahead of you leaning against a crate.

Boom Skull

After you head outside the ship, take the elevator up, and head through a few more hallways, you’ll come to a hallway filled with five or so Jackyls. The Boom Skull is in the next room, which you can see in the following screenshot.

It’s full of Brutes and Grunts, so clear them out first. Make sure to clear both levels of the room.

You can actually see the Boom Skull’s location as soon as you enter the room, though you have to be closer to the Skull before your scanner will pick it up. We jumped up to the second level, scanned, and hopped back down to the entrance to get the image above, showing the Skull relative to the entrance. (Don’t stand at the entrance and scan for the Boom Skull is what we’re saying.)

So jump up to the second level, and look up and to the right (with your back to the entrance). Press down on the D-pad to scan, and look for the outline of a skull. Ride the nearby elevator-like contraption up, and you’ll find the Boom Skull sitting in a little alcove.

Warship Gbraakon Banished Audio Log Escharum’s Testimony 01

A couple hallways later, you’ll come to the bridge where you’ll deactivate the stasis beam. Banished Audio Log Escharum’s Testimony 01 is on the upper level along the right side.
