11 Maps for Doom 2, all 'oldschool' in style and detail, and fairly short too (I'd never finish if I made them huge :P) UPDATE: Long overdue fixes to the texture problems in MAP10, and a couple things in MAP11.
Authors of editors used (see below), id Software, etc.
New from scratch
A while :P
DETH, Doom Builder, XWE, Wintex
Probably a few small texture misalignments here and there.
