Scattered throughout the open landscape of Zeta Halo are hidden skulls which once found offer a unique effect you can activate in the pre-campaign menu. This Skull Location Guide will tell you everything you need to know about them.
There are 12 skulls in total, some of which you will only get once chance to grab since you can only play each mission once per save file. This means if you miss a skull you will not be able to go back and retrieve it as you cannot replay individual missions. The game helps you find the skulls by making a spooky sound which gets louder the closer you get to it. Skulls in Halo Infinite are account-based, so if you collect a skull on Save 1 for example, you can still activate it on a fresh game in Save 2. It you want to attempt the LASO challenge, you will need to have collected all the skulls.
