Secrets

 * 1) Go south through the arch at the start - to your left is a secret door leading to a medikit. On multiplayer there is also a box of shotgun shells. (sector 111)
 * 2) The outdoor area surrounding the initial building has a lift to the east (with two tall red firesticks at the top) which leads to an area with teleporter-texture floors. Before reaching these floors, there is a secret door leading to an area containing several items including a chainsaw (accessed by pressing a switch to the west) and (by jumping back into the outdoor area) two berserks (one is not on easy skill, the other is multiplayer-only). (sector 313)
 * 3) After going through #2, jump across to the switch which lowers the chainsaw. Head west from here - after dropping down, pressing the northern wall lowers a lift allowing access to a backpack. Just before the backpack's lift is a secret door to the west which leads to a room with several monsters, a medikit, a computer area map, and a switch. The switch opens up a room with a blue key. (sector 291)
 * 4) After going through the blue door near the start, take the teleporter, head west through the door, then south to a room with a plasma rifle. There is a secret door in the north-west of this room (marked with a metal texture) leading to a passageway to the northern area. (sector 199)
 * 5) Towards the end of #4's passage is a secret door to the east leading to a medikit, an energy cell pack, and a shotgun guy (last two not on easy skill). (sector 39)
 * 6) There is a secret door on the south-west side of the outside of the yellow key building, leading to four energy cell packs. (sector 68)
 * 7) The northern part of the nukage surrounding the initial area has a secret door between two tall red firesticks leading to a radiation shielding suit, two cacodemons (hard skill only), 3-7 imps, two health bonuses, and a path to the northern area. (sector 104)
 * 8) The central pillar in the room behind the yellow door has a secret door in between the tall green firesticks leading to a shotgun guy, a partial invisibility, and an invulnerability (last two not on easy skill). (sector 31)
