Walkthrough

Map of Checkmate

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. Just before the lift leading to the red key, open the wall with the skull to get a plasma gun, an ammo clip, and energy cell packs. The switch here reveals a box of rockets. (sector 23)
2. Teleport from the red key area, then open the north wall to find a chainsaw, a rocket launcher, and rockets. (sector 55)
3. At the northeast room, go to the southeast corner to lower the central lift. Go south from that lift and into the east alcove to get a soul sphere. (sector 122)
