Secrets

 * 1) In the computer section at the start of the level, make your way to the south and flip the switch. Once it lowers, step on it and check the computer panel behind it to find a chainsaw. (sector 312)
 * 2) After you've entered the sewers, make your way to the large room with the teleporter at the back. Step on it and you'll be taken to a room with a chaingun, and after picking it up, the layout of the sewers will change slightly, with the entrance now being blocked off and a new exit path having been opened instead. Reach for the lift that takes you out of the sewers, but upon pressing it, turn back to see that another platform has lowered. Ride it up to obtain a backpack. (thing 125)
 * 3) After taking the lift out of the sewers, backtrack to where the original sewer entrance was to find there is now a blue keycard there. (thing 27)

Secret exit: After obtaining the blue key, backtrack to the starting area to find that the blue switch which used to be in front of the starting room has disappeared. However, a new switch has risen nearby: press it to cause a group of Hell knights to spawn in the corridors. After killing them all, the blue switch will appear again, and pressing it will lower two teleporters. Take either one to reach an out of the way room with two barons of Hell, and after you kill them, you will gain access to the secret exit switch that takes you to MAP32: Dark Secrets.
