Doom/E4M6: Against Thee Wickedly

This mission is on the difficult side, as you need to do the early portion rather quickly.

Clear out the initial maze until you reach the courtyard, and head into the secret on the left wall for a plasma gun. Enter the slime area on the left-hand side. Before picking up the radiation suit, kill any visible monsters. Enter the secret behind you to restore health and kill monsters there. Open the door in the middle and grab the rocket launcher, but run immediately back and avoid the baron of hell.

Grab the suit, and jump in the large pit. Lower the west side of the pillar by activating it (this is the direction you came from) and enter it. You will teleport infront of the chaingun, which you should take. Blitz forward and get the blue key, and dive back in the nukage pit. Lower the northern side, and teleport in. Run up the steps to open a door to your left, and flip the switch in the alcove. Run to the blue key switch to the right, and activate it. Get the orange key.

By now, your radiation suit is running out, grab a new one from the slime pit. Use it to reach the supercharge secret in the west, and head to the teleporter and go in the eastern side.

Approach the yellow key barricades, the head to the teleporter on the south of the room. Enter the yellow key building, flip they switch, and teleport out. Jump over the lowered barricades into the teleporter.

The red key is at the end of this corridor, and once you collect it, platforms will raise to make crossing the nukage pit easier. Head back to the eastern area, and enter the nukage to reach the other building locked with a red key. Open it and flip the switch.

Head back to the western area, and look for a corridor on the south. It should lead to a few medikits and an invulnerability, which you should take. Head to the eastern area, and go to the lowered Red key barricades. To the right is a BFG and beserk pack. Takethem and jump through the teleporter at the end. Use the BFG on the cyberdemon, and once he dies, you can use the exit.
