Halo Infinite Skulls unlock fun alterations to the gameplay. Skulls are nothing new to the Halo franchise, and have been a staple of fun easter eggs since the early days. If you enjoy being a completionist, or just want to try out some funky adjustments to gameplay, check these out.
There are 12 skulls in total, each altering the way you play the game slightly. These skulls are quite difficult to find on your own.
