This is the first version of Project Omega. This one is considerably worse than the one thats being redone right now, it should be done before the end of the year.
Project Omega is a full 32-level replacement for DooM 2. It Requires plutonia.wad to run. Simply extract the contents of the zip file into your source port folder, then drag Project Omega.wad and PO.bex over your source port executable. The bex file adds the intermissions for the Project Omega storyline. Enjoy.
