Your first priority is to reach the outpost at the top of the mountain. Follow the path counterclockwise around the island, running over the magma when necessary, and heading upward whenever you can. After one-and-a-half circuits, you’ll find a stairway leading up to the wall of the outpost itself. Go left to find the entrance.

Once inside the outpost, head straight across the intersection to reach a flight of stairs descending back out of the central building. Turn left, go around the corner, and follow the path around the outside of the outpost to a button which will open the passageway to the red keycard.

Head back the way you came and return to the intersection inside the outpost. This time take the northwestern path and pick up the red keycard at the end of the walkway.

The map exit is on the southeastern tip of the island next to the super shotgun. Run down the mountain to get there, then simply press the locked switch on the metal pillar, then press the second switch behind it, and finally step onto the revealed teleporter pad to end the level.

Other points of interest[edit]


  1. Against the south side of the outpost is an external walkway leading to a switch and guarded by a lone mancubus. Step off of this walkway onto the red ground (sector 458) to find a megaarmor nestled in the corner.
