Walkthrough

Map of Surface Zone

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.

Secrets

1. In the X-shaped room, after opening the teleporter to the northeast, approach it. Head back and to the northwest to get an armor shard, shotgun shells, and plasma cell. (sector 221)
2. In the south area, drop into the pit and go to the north end of the big structure. Press on the recessed wall to find a switch. After pressing it, head behind the yellow door and go to the east side of the rock. Climb up to get grenade packs, rockets, and pulse rifle rounds. (sector 53)
3. At the east side, enter the northwest room and use the switch. This opens the west door in this area. Go past it and to the wall to the west. Open it to get a medpack and rockets. (sector 220)
