About Doom 1 as 1 level, Doom 2 as 1 level with 3 comments by Ronnie42 on Feb 8th, 2014

Update:  15/9/2014

Blog from Feb:

Why isn't there a seperate engine-page for ZDoom or GZDoom? They are much more advanced then the vanilla Doom engine they derived from.

I knew Heretic is more attracting: the "only" FPS set in fantasy\medieval enviroment.
