Halo Campaign Evolved skulls and where to find them

A new guide for Halo: Campaign Evolved maps all 42 skull collectibles and explains what each one does.

39 skulls are hidden across 13 campaign missions, while 3 unlock automatically after finding two skulls.

The guide is useful for players chasing the LASO challenge and the Headhunter achievement/trophy.

It also outlines the gameplay modifiers tied to each skull.
