Essentials[edit]

Head past one or two shotgun guys and an imp to a door and open it; you will find yourself in a large outdoor area with the red keycard on a pillar in the center, guarded by imps and zombies (plus demons and spectres on Hurt Me Plenty skill level or higher). Go through the north door to a nukage pool with a platform holding a chaingun and a radiation shielding suit, then head east or west to some steps that lead up to a hallway with a switch. Flip the switch and fight your way past some more imps that are released to the east and west, then go back to the center area where you can now pick up the red key.

Fight off the shotgun guys that teleport in then head south to a red key door and open it, entering a hall with gray columns and computer terminals. Fight your way to the other side of the hall and enter a nukage trench on the south side, which you can follow east to some steps that lead up to a switch. Flip the switch and drop back into the computer hall, then step round the block in front of you to see that the middle terminal has lowered to reveal more monsters along with a second switch. Pressing this switch will open the three UAC signs on the other side of the trench releasing imps, shotgun guys and demons; after defeating them, enter the nukage and head west to find the yellow keycard sitting on a tiny plinth.

Leave the nukage and open the yellow key door in the north-west corner of the computer hall, which leads to a large chamber divided by a nukage pit. Head north up some steps and look right to see an alcove containing three or four imps and a button, which will raise a bridge across the pit when pressed. Kill the enemies that teleport in behind you then head across the bridge, killing any imps and cacodemons that block your way, until you reach the exit door on the other side. Open the door and flip the switch behind it to finish the level.

  4. In the south computer hall, find the terminal in the nukage trench that is blinking and shoot it. This will open a terminal to the west, revealing armor bonuses, rockets, health bonuses and a chainsaw. (sector 282)
