Frequently asked questions

How many Skulls are in Campaign Evolved?
The publisher catalog lists 42 Skull names and effects. 39 are hidden finds (three per mission). Adaptation, Armistice, and Reload unlock automatically after collecting any three hidden Skulls.
Which mission is each Skull on?
The primary source confirms three hidden Skulls per mission but does not map individual Skull names to missions or publish exact locations. This hub therefore tracks hidden Skulls in a global list and does not invent mappings.
Where do I track the ones I found?
Hidden Skull checkboxes share progress with the main collectibles checklist in this browser. Automatic unlocks are reference-only and never count toward the 52-findable total.
