This is a single level, Single Player/Co-Op wad. Turned out to be pretty damn big and probably quite tough, though I have made a bit of an effort to make it easier on 'I don't want to Die' and 'Hurt me Plenty'. Personally I think the level plays better on these settings.
The Deu Team for Windeu 5.24 and id software for DooM (of course).
New level from scratch.
Not a bug as such, but the lighting was done with a non-GL port in mind. If you play it on an OpenGL port you may want to mess around with the brightness/depthfog options to get the right effect.
