About This File
If you don't have it already, get the NEWBREED.ZIP first and follow the instructions. It is available in cdrom.com's 'combos' file area.
Then, download BREEDMAP.ZIP.
This contains three maps, death match only, a demo of me getting my butt kicked, and an installation for it all. This will replace Doom2's map 02, 03, and 04, so you can still play the map Breed comes with. After installing the New Breed, unzip the BREEDMAP.ZIP in your Doom2 directory, and type INSTALL3. That's it!! After that, just follow the instructions from the NEWBREED.ZIP.
