This is my first ever DOOM 2 WAD. I would be happy to take criticism for it, as I am just beginning to make DOOM mods. This is a short 7-level map pack that I made using GZDoom Builder and Slade3. Credits: VGMusic.com for the custom music Realm667 for custom monsters and weapons
To install, just extract the Zip file using winRAR or 7zip, then just find the .wad file and drag and drop it onto GZDoom. Then select DOOM 2 and it should be working. I would recommend using "Hurt Me Plenty" difficulty for this.
