Take the shotgun in front of you then turn left to see an imp in front of a switch, which will raise a bridge over the nukage. Cross the bridge (which will open alcoves to your left and right containing more imps) and flip another switch on the central platform, which will raise a second bridge leading to the south doorway. Go through the doorway and immediately turn left to find a switch that will raise a staircase, climb the steps and kill a baron of Hell that teleports in at the top, then head south into a passage leading to a platform with health bonuses and a chaingun guarded by one or two cacodemons. Flip the switch in the north-west corner to raise the platform up to a ledge with demons, then flip another switch in the south-west corner to raise the platform to the top floor where there are doorways with one or two barons of Hell behind them. Go through either doorway then head south past some imps to a wooden building, climb the steps and use the door at the top to finish the level and move on to E4M3: Secret Chapel.

Secret exit[edit]

After getting outside to the area with the exit building, head south through some large trees to find some graves. Look at the back side of the gravestone in the south-west corner to see that it has white streaks, press use on this side then quickly go round to the east side of the exit building where a white teleporter has lowered. Step on the teleporter before it rises to move on to E4M9: The Canyon.

Other points of interest[edit]

After crossing the first bridge from the start, head east into a room with a nukage trench then walk across the flesh growth to find a rocket launcher.


  1. Drop into the nukage at the start, then flip the switch by the north-west corner to lower a lift. When the lift lowers, open the wall to the left to get a berserk pack. (sector 48)
  2. Raise the bridge at the start, then go to the central platform and jump into the nukage to the south-west. Enter the teleporter, turn around, and open the wall here to get a chainsaw guarded by zombiemen. (sector 157)
  3. Pick up the rocket launcher at the east end of the map, which lowers two walls to the west. Go to the south-west wall and when it rises, open the south-west wall there to get a plasma gun. (sector 222)
