The shortest route involves going forward, into the room with a raised section and flipping the switch to raise stairs. This region has a few soldiers and imps.
If you feel you don't have enough ammo, or aren't confident with the berserk pack, head into the west section. The south (right) switch opens a door to a shotgun, while the north (left) switch opens a megaarmor, some shells, and a few monsters.
Once there. move towards the blue door to open a door leading outside. Head outside, and flip the switch, and return to the first room to grab the blue key. Getting the key opens an ambush door behind you with two chaingunners.
Head to the "exit", and flip the switch to lower the floor. Flip the switch on the far side, and get to the exit on the right.
If you need return to the rest of the map, look for a door marked with a blue torch in the exit room.
Ammo is rather tight on this map. If you fire, don't miss. The only good thing is that you get a beserk pack at the beginning of the map.
Secrets[edit]
- In the west room, flip the south switch. Head back the corridor and look on the east wall for a door outside. Circle around the pillar and get a shotgun.
Deathmatch[edit]
If you spawn outside, whether in coop or deathmatch, circle around the water area to get a BFG, Chaingun and rocket launcher.
- Rocket launcher in the blue key area.
- Cyberdemon is outside in the northern area.
- BFG is at the exit.
