In Halo Infinite, Spartan Cores upgrade the Master Chief’s newfound abilities, such as the grapple. There are 45 Spartan Cores spread across all four acts, with each island containing an act.
17 Spartan Cores are found in the second act, three of which are completed during Mission 3: Outpost Tremonius. All three are claimable before moving islands, or players can grab these Spartan Cores after clearing Act 1.
