Collectibles abound in Halo Infinite’s campaign, some missable and others accessible in the open world outside of the main missions. The first thing to note are Skulls – you can check out the locations for all of them in the video guides below by the Halo Completionist. However, note that Skulls in missions like Silent Auditorium, The Command Spire, Foundation, Repository and Warship Gbraakon can be missed. Since there isn’t currently a way to replay story missions, it’s best to get them while you have the chance.
Along with Skulls, other collectibles include Spartan Cores, Forerunner Archives, Propaganda Towers, and Mjolnir Armories. Here’s the total number of each that can be found in the open world:
- 33 Mjolnir Armories
- 45 Spartan Cores
- 8 Skulls
- 7 Forerunner Artifacts
- 38 Propaganda Towers
You’ll also find a number of UNSC and Banished Audio Logs while exploring. These are worth picking up since they fill in a lot of the blanks between Halo 5: Guardians and Halo Infinite, discussing the fate of certain characters and whatnot.
