Just unzip and use Brutal FreeDoom with any mapset that uses vanilla weapons and monsters with GZDoom 4.0 or higher, or LZDoom 3.88. Also works on Delta Touch. The other PK3 is DOOM style version that is very similar in gameplay. bonus goodie basically.
Load PK3 with any Doom or FreeDoom IWAD and PWADs. GZDoom or LZDoom needed. Kept light to mix with Texture Mods, HUD mods or Gore Mods. Has custom Gore in it, but still compatible with Nashgore. It supplies Weapons, Monsters, Liquids and Gore.
