Blue key

Grab the health bonuses and drop to the outside area. Turn left and walk up on the stairs. Enter the door ahead to enter a cargo room. Go to the northwest of the cargo room. Notice a lone brown crate. Walk around it and press a skull button located on the southern side of it. This will build the stairs leading to the top of another crate. Walk up on these freshly built stairs. Now, jump over numerous crates to get to the southern part of the crate room. In the very south portion of this room, you can see the blue skull key located on grey crates. Also, notice a small grey crate located in the southwestern corner with shotgun shells on the top of it. Step on this crate to lower the blue skull key. Grab the key. You can also press the skull switch near the blue key crates to open a wall nearby. Behind this wall is a teleporter. Use this as a shortcut to get back to the northern portion of the crate room.

Red key

Backtrack from the crate room to the outside area. Near the stairs leading up, open the blue door. Inside, walk upstairs. Go to the north of the room and lower a lift to get higher. From here you can notice the red skull key. It can be obtained from that side. However, you need to build the stairs up that lead to this key. To do that, first enter the door to your right. You now need to press four switches located in various places here. Each switch will partially build the staircase for the red key and can be pressed in any order:

1) After you have just entered this area, notice a red torch which throws its red light on the wooden wall. Open this wall to enter a dark closet with several barrels and imps. Press a skull switch to open a wall here. Enter it to find yourself inside a cage where you can see a previous room through. Go to the southeast of the cage and press the first button. Backtrack to the room where you have seen the red torch.

2) Near the red torch, descend down to the hall with numerous columns. The northeastern column has a button on its northern side. Walk around and press this second button.

3) In the hall of pillars, proceed south. Lower a lift in the west of the hall. Press the third switch in the caged room.

4) In the hall of pillars, press the fourth switch in the south of the hall, right before the staircase.

When the stairs are made, lower the lift near them and walk up on them. Turn left and grab the red skull key. Backtrack to the outside area through the blue door.

Yellow key

Near the blue door, go all the way north to the red skull bars. Open them and proceed north. In the nukage area, walk upstairs. In the dark room, drop on the platform north in the nukage area. Here, walk up the stairs leading northwestward. Press the skull switch. It will lower both the key pedestal and a path for proceeding further. Grab the yellow skull key.

Normal exit

In the nukage pool area where you have grabbed the yellow key, an entrance leading to the mines is open now (east). Go to the northeast of the nukage area and enter these mines. Go to the very east cleaning the place of the enemies. Turn right and go south to an open area. Between two torches is a teleporter underneath. If you enter it from the northern side you will find yourself in a place with numerous health bonuses and a megasphere. You can see a cage in this area. Go past it and enter inside to the west. A wall will open. Eliminate several shotgun guys and head into yellow door. Turn left and go to the north of the corridor. Dispatch the barons of hell and press the switch in the nukage place. A wall is open in the southeast in the corridor. Go there. Walk upstairs and drop. Turn left and enter a caged room. Enter a teleporter. Turn left here and open the door requiring yellow key. In the exit room, head into watery exit pool.

Secret exit

In the northern part of the map, you proceed through the mines path after the nukage pool area. In these mines, when you meet the second pair of wooden pillars, turn right and open the wooden wall south. Inside, go left (east) and clean up the room of imps first. Backtrack and use the path to the right (west). Dispatch the baron of hell. Notice three torches in this room. Press use on the southern one to lower a platform. Quickly, backtrack to the room full of imps. Step on the lowered platform to the north of the room. If you are too late, get back to the room with three torches and repeat. Turn right and head into teleporter ahead marked with exit sign to get to MAP57: The Marshes.


  1. The closet which contains secret exit teleporter is counted as secret.
  2. After collecting the blue key, turn and press the switch to open the wall. Use the teleporter pad to find yourself on one of the crates. Do not drop down and turn around. A wall differs from the other ones significantly. Press use on it, then drop down. A western wall in the crate room which is also visually differs from others should now be opened. Enter it to find yourself in a room with four blue torches and a soulsphere.
  3. With the blue key collected, enter the blue door. Inside, turn right and use the lift leading south. From here, drop on to the ledge with the baron of hell. The wall ahead should open now. Kill the shotgun guys and enter this wall. Inside, you can collect a medikit, a combat armor and another baron of hell.
