Secrets

 * 1) After going through the first two doors, you will reach a short corridor.  The western wall has a secret door leading to four armor bonuses, an armor, and a box of shotgun shells.  Both the door and the room count as separate secrets. (sector 5)
 * 2) See #1. (sector 6)
 * 3) After going through two more doors, press the section of the western wall with the four pictures.  It opens, revealing two health bonuses, two armor bonuses, and a box of shotgun shells (three in multiplayer). (sector 12)
 * 4) En route to the blue key, you will cross a nukage pit.  After doing so, there will be a secret door on your left (marked with a brown texture) leading to an armor, a medikit, a chaingun, and three boxes of bullets (six in multiplayer). (sector 68).
 * 5) Jumping down into the eastern part of the nukage pit allows access to an area with 8 shotgun shells, a rocket launcher, two boxes of rockets (five in multiplayer), a box of bullets (two in multiplayer), and a medikit.  There is also a lift to return to normal territory. (sector 34)
 * 6) Entering the area surrounding the yellow key room opens up several traps.  The north-western one has a secret door in its north-west corner leading to a health bonus, an armor bonus, a medikit, and a soul sphere.  There is also a switch here. (sector 97)
 * 7) The switch in #6 opens up a corridor accessible from an earlier area.  This corridor contains a box of bullets, some health and armor bonuses and leads to an outdoor area with some shotgun guys, a partial invisibility, a box of bullets, and three boxes of rockets (six in multiplayer).  The corridor counts as three secrets. (sector 129)
