Secrets

 * 1) In the north-west of the level is a secret door (marked with a misaligned texture) leading to 4 shotgun shells and a blue key. (sector 52)
 * 2) In the room south of the exit, the southern wall has four protruding parts. The eastern one lowers on pressing, revealing a teleporter to an area in the east. The sector south of the teleport destination, containing five boxes of bullets, counts as a secret. (sector 26)
 * 3) From the crossroads south of the blue door, head east. There is a secret door on the south wall (marked with a misaligned texture) leading to a radiation shielding suit. (sector 136)
 * 4) The room before the yellow key room counts as a secret and is impossible to miss. (sector 66)
 * 5) The yellow key room counts as a secret and is impossible to miss. (sector 69)
 * 6) On the path to the red key, just after the nukage, is a secret door to the east leading to a backpack. (sector 138)
 * 7) After taking the teleporter mentioned in #2, head north-east then hook round and head south to a switch. This switch lowers several walls in the opening area, revealing a ledge in the south-west with seven imps and two barrels. There is a secret door to the west here (marked with a misaligned texture) leading to two medikits and four rockets. (sector 14)
 * 8) Shoot the north wall of #7 - it opens, revealing a box of rockets. (sector 17)
 * 9) After lowering the walls (see #7), there is an area with four small nukage pits. This area has a secret door on the eastern wall (marked with a misaligned texture), leading to a teleporter to a nearby ledge allowing access to four alcoves with items. (sector 112)
