with brutal doom i dont think, becuase my mod is not compatible with pwads using acs or decorate, becuase that cause problems with the scripts. But the mod is compatible with vanilla pwads.
I have played this a lot and let me tell you it's tough, RE and Doom don't really mix seeing as you're constantly getting knocked down by enemy projectiles.
I think I should upload playthroughs of Ultimate Doom.
Extract the files and put all into your doom foldier and later execute (is very necesary) the MS-DOS files:
MS-DOS called "mercenaries with music" this is for zandronum and execute the wads: hunk3.wad + recodesst.wad and mercmusic.wad. This is for play with the music of the character selected.
