Secrets

 * 1) From the start, run directly ahead under the 'O' sign.  You will land on a ledge, at the eastern end of which is a secret door leading to a megaarmor. (sector 26)
 * 2) The long east-west corridor just before the red key area has a secret door on its north side (marked with a different texture) leading to a stimpack, a medikit, a box of bullets and a box of shotgun shells.  There is also an imp here on medium and hard skills. (sector 36)
 * 3) Just before the arena is a room with several boxes of rockets.  There is a switch in this room which opens up a teleporter to the north-east of the level, as well as opening a door in that area, leading to a previously inaccessible area. (sector 83)
 * 4) After going through #3, head west to a lava room with a hexagonal platform then south where you will find a switch.  This switch opens up two rooms to the east, one of which contains a plasma gun.  Entering this room opens up a path to the north-west of the hexagonal platform, leading to a room with several monsters and a soul sphere in the centre.  Press the switch on the southern wall of this room - it lowers the soul sphere. Collecting the soul sphere opens up a trap to the south and also a switch in the western part of this room.  This switch opens up a room in the arena area, encountered en route to the yellow key, containing a BFG9000 and an invulnerability. (sector 139)
