In Halo Campaign Evolved, "The Silent Cartographer" mission offers players three skulls and one terminal to discover. This mission follows Master Chief's search for the Halo's map after rescuing Captain Keyes. The level is notable for its visually striking beach environment.

Bandana Skull

To find the Bandana skull, which grants infinite ammo and grenades, players must first clear enemies after arriving via Pelican and then acquire the Warthog delivered by Foehammer. Drive the Warthog around the island's perimeter toward the objective marker. When the marker directs you indoors, do not enter. Instead, locate a cave on the right side of the structure. The Bandana skull is situated on the floor within this cave.

Acrophobia Skull

The Acrophobia skull, which provides players with "wings," is found by continuing around the island from the Bandana skull's location towards the objective. Players will encounter a large, ramp-shaped rock. Behind this rock, after clearing some enemies, a path leads up toward the island's center. Follow this path until you reach a structure guarded by two Hunters. After defeating the Hunters, approach the base of the structure and ascend a diagonal beam. At the top, partially obscured by leaves and branches, is a flat section where the Acrophobia skull rests at the highest accessible point.

Status Update Terminal

Progressing from the Acrophobia skull's location will lead players into another Covenant structure. After defeating two Hunters in a small room within this structure, continue onward. Although Cortana may prompt to use a terminal for security override, proceed past it. The "Status Update" terminal is located at the very end of this path, situated behind a table.

Hip Fire Skull

The Hip Fire skull, which disables all weapon zoom functionality, is found after disabling the security override. Continue following the objective deeper into the structure until you encounter another pair of Hunters. Once they are defeated, look behind them for a brightly lit stairwell with blue lighting effects. Proceed to the edge and look down; the Hip Fire skull is on a platform below. Players can simply drop down to collect it. The player in Halo: Campaign Evolved looking down at the Hip Fire skull.
