Secrets[edit]

  1. Enter the pyramid and go southwest towards a sarcophagus. Shoot the switch to the north of it and press another switch to the west of the sarcophagus. Go north to the new room with bars to the west and the Horus' eye on the wall to the east. Press on that wall to find a shotgun and shotgun shells. (sector 91)
  2. Head south from where the red key is into the hall and go down the steps. Press on the east wall right next to the viscera to find a box of shotgun shells, a medikit, and an armor. (sector 237)
  3. In the large chamber with columns in the north part of the map (north of the yellow key), head west to the circular staircase and climb it up. Open the door southeast of the stairs to find the area with two candles in the southeast and southwest corners. Approach the southeast one and find a hidden switch near it. Press it to lower a block to the east. Drop down and head north. The hieroglyph wall will lower in front of you, taking you back to the large chamber. Entering it will lower a hieroglyph column in the northwest corner of the area. Ride the column up to the alcove with shotgun shells and press the north wall here to reveal a megasphere. (sector 298)
  4. From the yellow key, head south and lower the hieroglyph wall. Head east and south, but do not go up the steps. There is a switch at the base of the steps. Press it and run north and east to find a backpack. (sector 258)
  5. In the square room with the square pool of clean water (northwest of the blue bars), press on the southwest corner to reveal a switch. Shoot it to open the corridor in the east wall with an energy cell pack and an armor inside. (sector 719)
