This is the smallest map I've ever made.  Inspired by some of the early Doom II levels (mainly The Focus and The Crusher), this factory-themed level can be beaten in around 5 minutes (my best time is 1:15).  It's got action, traps, and secrets - everything you could want in a tiny Doom level!   Compatibility: Doom II - Vanilla (tested with Chocolate Doom and DOSBox). Intended to be played without freelook, jumping, &c. All difficulty settings supported. Multiplayer implemented but untested.   Download: Production Line.7z     Screenshots:
