Polygon’s guide explains where to find the three skulls and one terminal in “The Silent Cartographer” mission in *Halo: Campaign Evolved*. The collectibles offer gameplay modifiers or extra lore, and can be collected while progressing through Master Chief’s search for Halo’s map room.

The Bandana skull, which grants infinite ammunition and grenades, is in a cave beside the first large Covenant structure rather than inside it. Acrophobia, which enables flying, is atop a structure near two Hunters; the Status Update terminal is behind a table beyond the security-override terminal; and Hip Fire, which disables weapon zoom, is on a lower platform beside a brightly lit stairwell after a later Hunter encounter.
