Map of Alpha Sector

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.

EssentialsEdit

After clearing out the main room, press the switch in the red-walled room to reveal the yellow key. Collect it, whilst remaining vigilant for newly spawned-in monsters. Fend off the suicide bombers, Hell knights and cacodemons inside the yellow doorway room, and press the button to lower the path to the red key. From there, head to the red door, be wary of the troll trap as you activate the exit door, and press the newly-revealed switch to truly open the exit.

Other points of interestEdit

SecretsEdit

1. Pressing the switch to reveal the yellow key also lowers a wall back at the starting point of the level. Travel back there to find a backpack. (sector 210)
2. After uncovering the false exit, press the wall behind the hanging marine to find a passageway leading out to a soulsphere and a rocket launcher. (sector 165)
3. At the exit to the map, instead of pressing the switch inside the train carriage, instead run east, down the tracks, to find a megaarmor. (sector 185)
