Standing slightly northwest of the exit door, looking east.

Entering the hidden area behind the imp platform, then immediately turning to face the right-hand wall.

Looking toward the imp platform from the south end of the zig-zag walkway.

Viewing the zig-zag room from the north entrance.

Slime trails may be visible in the following locations (see screen shots below):

Press on this section of the wall ( X) to be taken to the Xbox-exclusive secret level, E1M10: Sewers. Secret exit : In secret #1, head to the very east of the courtyard, and then follow the northern wall until it begins to bend northwest. ( sector 87) At the end of the hallway is a fake see-through wall, the first such wall in the game. Run and you can catch it before it goes up. As you cross the shadow line ( I), a lift will lower in the shotgun alcove ( J), visible from where you are standing.

After opening secret #2, walk toward the north end of the zig-zag room.

The platform with the imp(s) has now been lowered, yielding access to a secret room ( H) containing a shotgun.

After having entered the dark room with the exit door, return to the zig-zag room.

Activate the wall to gain access to the courtyard with the blue armor.

In the corridor at the end of the zig-zag room, a portion of the west wall is colored differently and has a corpse lying next to it ( G).

To register secret #1, however, it is still necessary to activate and walk through (from either side) the differently-colored wall described below. These new doors were likely added to improve gameplay in deathmatch mode since they provide two extra ways to reach the rocket launcher.

As a player walks through this door, another large door will open up, making it possible to get to the courtyard from the computer room. The north pillar has a switch ( E) which opens up a door to the courtyard ( F) with the blue armor and, in multiplayer mode, a rocket launcher. In the alcove leading to the green armor, there are two pillars. They can cause quite a bit of damage due to their awkward positions, but on the positive side killing them gives you an early shotgun.

If you play on Ultra-Violence or Nightmare!, watch out for the sergeants that guard it there are two by the armor and one behind each of the pillars by the staircase. To the left of the start room is a platform with green armor on a pedestal ( K). Go through the door on the far side, then through the exit door into the final room ( D). Proceed through this room and through a short passage, and you will enter a large room with a nukage pool across which goes a zig-zag bridge ( C). From the start point ( A), walk forward across the blue floor, turn right, and go through the door into the central computer room ( B). There are no keys in this map, so you can go directly to the exit. Sector numbers in boldface are secretsВ which count toward the end-of-level tally. Letters in italics refer to marked spots on the map.
