Secrets

 * 1) From the start, go right and use the wall with the poison symbol on it to reveal a hallway, eventually taking you to a chaingun and a berserk pack. (sector 29)
 * 2) In the red key room, use the computer panel to the left of the switch to lower a lift in the southeast corner of the room. Run to it quickly to retrieve a soul sphere. (sector 109)
 * 3) From Secret #4, there is a shootable switch to the east. Shoot it for a block to rise, allowing you to go onto the next platform, which contains the blue key, a radiation suit, and some armor bonuses. (sector 115)
 * 4) After getting the red key, open the red door near Secret #2 to find a lift switch, but look towards the computer terminals on the right wall to find a tucked-away switch. Use this one to reveal a switch in Secret #2, then go back there and flip that switch for a lift to the south to lower. Take this lift up for a megaarmor and some health bonuses. (sector 260)
 * 5) From where the yellow key is located, look towards the fountain to see a tiny step allowing you to get onto the fountain. From there, jump west and outside where you can collect health and armor bonuses as well as a computer area map. (sector 278)
