Secrets

 * 1) Sector 110
 * 2) Sector 237: In the computer room near the centre of the map. On the west side of the computers, use the one green texture. It lowers, leading under the computers. While other things, such as a light amplification visor can be found in this secret, its primary purpose is its involvement in getting the blue key.
 * 3) Sector 391
 * 4) Sector 533
 * 5) Sector 653: South of the red keycard, there is a narrow corridor, guarded by zombies on platforms, with a lift at the end. Lower the lift, and as it rises, jump on to the west platform, and take the rocket launcher.
 * 6) Sector 795: After one of the yellow doors, there is a room with a super shotgun, which will reveal a cacodemon when taken. In this same room, press the green computer texture with the flashing light. The adjacent wall lowers, revealing a corridor with a soulsphere.
 * 7) Sector 876: South of the secret in sector 653, there is a room with more computers and a floor with wiring. In the north of this room, there is a wide computer panel, monitoring a celestial body of some sort. Activate this to lower some nearby pillars, giving access to a plasma rifle.
 * 8) Sector 1036: In the far north of the map, a usable wall is indicated by multiple blue lights. A green armor is on the other side.
 * 9) Sector 1337
