A moderately-sized techbase heavily inspired by Ultimate Doom episode 2 (especially Deimos Lab). The difficulty is easy/medium, and is a 5-10 minute play. This is designed for single player, but functions well in cooperative too.
As this is my first release, the map is a bit underdetailed, and was originally completed in May 2005. I made a few changes to it before uploading, but these were mostly cosmetic (light values, textures) so as to keep the 'first map' feel.
Belial, Hobbs, and the rest of #DMClub for giving me feedback on the level and being awesome in general, Björn "Vader" Ostmann for a ZDoom script that I unfortunately cut out at the end to keep compatibility, and id Software for Ultimate Doom (in particular, Sandy Petersen for episode 2).
New from scratch

Textures may appear to be misaligned due to the nodebuilder used (ZDBSP), although they will display correctly in ZDoom-based ports.
