Walkthrough

Map of Trench altar

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. At the north end of the map is a megasphere. Shooting the button in the alcove in the room to the south sets off the mines allowing you to get it. (sector 69)
2. Take the west path from the start and head east into a tiny path to get a berserk pack. (sector 71)
