Map of Skyfire Research
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.


You start at the entrance to a building, which has three doorways leading away from it; the north and south doorways are initially sealed but will open later. Behind you are two passages - the north passage leads to the core, while the south passage leads to the item pads.

Monsters will initially spawn from the west side of the level, head north-east or north-west around the ion cannon then proceed east until they reach the passage leading to the core. From wave four monsters will also spawn from the north-west corner, and from wave seven monsters will also spawn from the south-west corner; all paths will converge at the building entrance.

A shotgun is placed in front of player one as the level starts.
