Secrets

 * 1) Just before you reach the second tower that holds the exit, look back at the last square column of the lava to find a switch. Press it, then go to where the red key is located. There will be two openings to the north, just above the lava river. Approaching either of these openings opens up the columns and creates a bridge allowing you to cross to the other side. You can collect the plasma gun at the end of this area. (sector 4)
 * 2) The far eastern corner of this map hides a berserk pack. (sector 213)
 * 3) The northern part of the main tower has damaging flesh pits. The biggest one has an arrow pointing southwest. Instead of directly following this arrow, go along the path just to the right of it. Follow it to a switch, then quickly run back northeast to the flesh pit to notice that the ledge that had imps on it has lowered. Get on this ledge quickly, and when it rises, open the wall at the end to get a computer area map. (sector 271)
 * 4) In the northeast part of the main tower with the damaging flesh pits, a shotgun guy may attack you from behind a fake wall. Go around to where two boxes of ammo are located and face east, then go through the wall to find the secret, which holds a box of rockets. (sector 272)
