MAP11: Refinery (Console Doom)

MAP11: Refinery is the eleventh level for console versions of Doom, based on the original E2M3: Refinery with modifications made to adapt consoles' limitations. The original authors of the map are Tom Hall and Sandy Petersen. The map first appeared in Atari Jaguar version, and was later used in the 3DO, Sega 32X, Game Boy Advance, Sony PlayStation, and Sega Saturn versions.

 * The staircase passage with plasmarifle, which connects the blue keycard room and metal room next to the marble hall, has its ceiling higher than the sky of the lava room. This causes the scenes in the staircase and the blue key room to render above and over the sky texture (this does not normally occur in the PC version and the console versions other than PlayStation and Saturn, which use polygon rendering technique).

Comparison of versions
Compared to the PC version, aside from simplification of level geometry, the following changes have been made:

All the thin walls in both nukage-filled areas have been removed or severely simplified.

Music
The map uses the following music tracks:
