All Spartan Core locations in Reformation in Halo Infinite

The final act of Halo Infinite has more than a few arcs clashing together in a climax, but Spartans would be remiss to allow that to interfere with grabbing the final few Spartan Cores to ensure Master Chief is ready for the final showdown.

With a heavy hostile presence scattered about the Reformation arc, and the second-largest land mass for the Master Chief to contend with in the game, slow and steady is the idea for chasing down the final 15 Spartan Cores.
