The door straight ahead that says "SIMU EXIT" is the exit, but you need the red key first. To your left are three lifts, take any one of them and proceed north as much as you can into a very large room. Go downstairs from there to reach a room with a red floor. Go around it to the left towards the broken vent and clamber into it. Proceed through it out another broken vent into a vine-covered room. Head for the stairs to the northeast and climb up to find a chaingunner and the red keycard. Backtrack to the exit, and then press on the panel furthest to the right to open the exit.

Other points of interest[edit]



  1. In the southernmost room east of the lower hallway (accessed from the eastern elevator in the first room), there is an upside-down cross on the northern wall. Press on it to find a chaingun, a partial invisibility, a berserk pack and three bullet boxes. (sector 71)


  1. Ride down the central elevator in the first room. Descend either set of stairs, then the one to the north. A part of the eastern wall does not have any computer control. Open it for a computer area map. (You have to run against the opened wall to grab it.)

Routes and tricks[edit]

As with a number of other levels in Icarus featuring ship and simulation exits, you can perform a suicide exit in the exit room. However, the level's only rocket launcher is multiplayer-only, so you must use a monster. To do this, get the heavy weapon dude to attack you until you are nearly dead, open the exit room door, and then run toward the exit while he is shooting at you. With luck, you will be killed by a bullet mid-run while you are close to the barrier. If performed correctly, your body will slide under the barrier and into the simulation portal to end the level.
