Walkthrough

Map of Thirty Seconds to Earth

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.

Essentials

You begin in a circular arena where enemies are already attacking. Head to the southwestern part of the room and press a switch to open a door leading to a corridor in the northwestern section of the level. The corridor is long and contains three mech spectres, two double chaingunners, two dark imps, and one plasma zombie. At the end of the corridor, you will encounter four kamikaze enemies and another mech spectre, as well as a 30-second door.

Near the exit, a plasma rifle and energy cell packs are provided, allowing the player to eliminate any remaining enemies after the 30-second timer expires.

Secrets

There are no official secrets on this map.
