Searching for Halo Infinite skull locations? After the initial multiplayer release not so long ago, the campaign has finally arrived, and though co-op isn’t coming until mid-2022, there’s still lots of fun to be had wandering around the open ring world—see our Halo Infinite review for more details.
Halo Infinite skulls are one of the ways that you can tweak your campaign. Just like previous Halo games, these collectables can be discovered, and each of them unlocks a modifier that you can activate in the pre-campaign menu. These range from bigger explosions to classics like Grunt birthday party, which causes a little celebration every time you headshot one.
Finding each skull is a somewhat tricky task made even tricker by the fact that there’s currently no way to go back and replay individual missions. This means that if you miss a skull during a story event and don’t have an appropriate save, you’ll have to play the whole campaign again to get back to that point. That said, here are all of the Halo Infinite skull locations.
All Halo Infinite skull locations
In this list, you’ll find the location for each Halo Infinite skull, as well as its name, and the modifier it adds to gameplay.
- Name: Boom
- Effect: Doubles explosion radius
You can find the first skull during the opening mission, but it’s very easy to miss. On the Warship Gbraakon, you’ll find yourself in a long room with a floor above you and three moving lifts to your right. Grapple up to the second floor through the gap in the ceiling and jump onto the middle lift. The Boom skull is sat on a container to your right if you’re facing the wall.
- Name: Cowbell
- Effect: Acceleration from explosions is increased
The second Halo Infinite skull is found during the mission at the Foundation. It’s a tough one to get hold of, let alone find. Once you’ve picked up the Weapon, you’ll get to an area with holograms. Keep going until you reach a vast room, head to the left until you find the point where the room opens out and use your scanner to locate the skull high above you. It’s tricky to get to, but keep using your grapple to get higher, and you’ll eventually reach it.
- Name: Catch
- Effect: Enemies throw and drop more grenades
Once you reach Zeta Halo’s open world, head to the northern section of the map. You should find a canyon to the northwest of Outpost Tremonius. There are enemies here, but once you’ve dispatched them, you can recover the Catch skull from a tree stump.
West of FOB Alpha
- Name: Fog
- Effect: Disables motion tracker
This skull is found in a small cave on the very western edge of the map. It’s almost directly west of Halo Infinite FOB Alpha, and you’ll have a much easier time if you take a vehicle to reach it. Look for the hexagonal columns and search for a ledge along the western edge. The Fog skull is located inside an opening above the narrow shelf, among several abandoned helmets.
- Name: I Would Have Been Your Daddy (IWHBYD).
- Effect: Rare combat dialogue becomes more common
The IWHBYD skull is found on top of The Tower, and if you’re paying attention to your surroundings, you might also spot the Craig easter egg nearby. The easiest way to get up to the top is to take a flying vehicle. Once up there, look for the collection of containers around the central structure, and you’ll find the skull sitting on top of a chest.
South of The Tower
- Name: Blind
- Effect: HUD and weapon do not display on-screen
The next skull is found to the south of The Tower, where you picked up the last Halo Infinite skull. You should see a deep ravine here, so again, use a flying vehicle to explore beneath the surface. The Blind skull is located inside a well-hidden cave here. Use your scanner to help pinpoint the exact location.
Near anti-aircraft guns
- Name: Thunderstorm
- Effect: Upgrades the rank of most enemies
The Thunderstorm skull is another tricky one to locate. It can be found on top of a hexagonal column, pretty much in the middle of nowhere. It’s close to the area with the banished anti-aircraft guns, and you’ll need to use your scanner to find its precise location. Once you’ve found the AA guns, look around for a cluster of hexagonal columns. The one you’re looking for is pretty small and stands slightly away from the main formation.
- Name: Black Eye
- Effect: Your shields only recharge when you melee enemies
The Black Eye skull is found in a cave behind a tall waterfall. The opening is pretty small and hard to spot, even when you’re close—look for the dark shape of the entrance on the right side of the waterfall, about halfway up. Once inside, find the skull sitting on top of a stalagmite at the back of the cave.
- Name: Famine
- Effect: Weapons dropped by enemies have half the ammo they normally would
This skull is found at the far eastern edge of Zeta Halo. The area you’re heading to looks like a small island on your map. The Famine skull is found on a ledge next to a dead elite. The bright yellow armor makes the location slightly easier to spot from the sky.
- Name: Mythic
- Effect: Enemies have increased health
Once you’re on the Command Spire mission, you’ll reach an area where columns are passed through light and etched with markings. There ‘s an opening in the ceiling, and you’ll need to grapple to one of the moving columns, then again through the hole above you to reach the darker area above. From here, there’s a hard-to-see door higher up again, so use your grapple to reach it and retrieve the Mythic skull from the room at the end of the corridor.
- Name: Grunt Birthday Party skull
- Effect: Grunt headshots lead to glorious celebrations
The Grunt Birthday Party skull is found during the Repository mission. You’ll see a massive room with a terminal in the center. Activate the terminal to get a light bridge to appear, leading to one of the doors on the room’s outside wall. Instead of crossing it, grapple across to the door on your right. Grab the power seed from inside the room at the end of the corridor and take it to the room on the opposite side—that’s the other door with no light bridge leading to it.
It can be pretty tricky getting the power seed to its destination. If you drop it, it’ll respawn in the original location. You can throw it, though, so with a lucky aim or two, you should get it where it needs to go. Once you’ve placed the power seed in the device in this room, continue with the mission as usual.
You’ll soon arrive in a room with golden metal plating on the walls. If you look up on the wall ahead, you should see an opening you can use your grapple to get to. If you didn’t place the power seed earlier, this opening would be inaccessible. There are a couple of elites to deal with here, but once they’re taken care of, you’re free to grab the Grunt Birthday Party skull.
- Name: Bandana
- Effect: Grants unlimited weapon ammo and grenades, and removes equipment cooldowns
The last skull is found during the Silent Auditorium mission. Don’t kill any sentinels when you reach the large room, or the last skull won’t spawn. Instead, continue through the level until you get to a couple of light bridges. Activate them and make your way across and into a long room. The Bandana skull is located on top of the structure in the center, so grapple up there and pick up your prize.
