This is a demo for a single player 32 level campaign for doom 2. this demo includes the first six levels. uses assets from the PSX total conversion mod like the monster sprites, gun sounds and music. Should run fine with ZDOOM, GZDOOM, LZDOOM, QZDOOM, BOOM, AND ZANDRONUM. works great with ZDL. works fine with both brutal doom and project brutality as long as the mod is last on the load order and this wad is 1st (but removes some sound effects in place of the brutal sounds.) Must use jump and crouch features for getting certain secrets. can be played without free look if you're wanting a more classic feel. RECOMMEND USING HARDWARE for the light effects and other enhancements but should be just fine on software. just drag this and DOOM 2 onto zandronum or whatever source port you're using and you're good to go!!!!
