Walkthrough

Map of Refinery

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. Lower the brown stack of crates in the northeast playing area to reveal a passage. Flip the switch in this passage to lower a lift next to you. Ride this lift up, and at the top, quickly run straight west and flip the switch here (this switch closes after 1 second). Now go to the southern section of the level and jump into the nukage. There is an open door in the northeast corner, concealing a teleporter that takes you to a megaarmor on top of a crate. (sector 141)
2. One of the walls in the southeast part of the playing area has a candle in front of it. Open this wall to find a plasma gun. (sector 386)
3. Lower the brown stack of crates in the northeast part of the playing area, then go through the passage that is revealed to the stack of crates leading up to the super shotgun. (sector 432)
