Deimos maps
This level occupies the map slot E1M2. For other maps which occupy this slot, see Category:E1M2.

E1M2 is the second and last map of Deimos. It was designed by Jeremy Lee.

It exists in two separate versions, both in the same zip file - the original version, and an upgraded version which is saved as UGRADE.DUD. The latter can be played by simply changing the file extension from .dud to .wad.

All details below relate to the upgraded version.

This level stands out for not giving you weapons during much of the playthrough, so you must provoke infighting and hide from most of the combat.

You start the map at a junction. Go to the left side, to the west. Keep left and go down an elevator to the toxic sewers. Take a rad suit and follow the toxic river until you reach the bottom. Don't open the door on your left, as it is full of demons and you don't have enough weapons. Take the right side and continue to a marble room, there you will find the blue key.

Now go back to the wooden room. Beware of the tight corridors and the baron of Hell. Continue until you reach a red floor, which will immediately teleport you to the yellow key area. You will return to the beginning of the map. Now follow the same path you took at the beginning, but go up the stairs to the right, at the bottom and go through the yellow door. You will enter a computer room. Continue to the center and up the stairs until you reach a switch. Then go down the left side and you will see another switch. Now go right along the path in front of the switch and you will find the blue door. Inside you will find the red key, a switch, and multiple weapons.

Go back to the center and into the red room. Press the switch that opens the door in the east corridor. Inside is the last group of enemies and the exit.

Other points of interest[edit]


  1. The room before the blue door has an alcove to the east with a switch. Press this switch, then go through the teleporter leading out of the blue key area. A door is now open leading outside - a part of the western wall here lowers on pressing to reveal a backpack, a box of shotgun shells, a rocket launcher, a rocket, and two medikits. (sector 124)
