The project was designed to be a creative exercise in building levels around the original map titles for all 36 maps of the Ultimate Doom with an increasing emphasis on creating challenging but enjoyable maps that will even given experienced veterans a stern test (Especially for an Ultimate Doom megawad and especially so for episodes 3 and 4). All maps are built to a limit removing (complevel 3) format and are beatable from a pistol start, difficulty setting are included, but some may need a little refinement to pitch the difficulty with more precision. Co-op starts are included but anything beyond this will be patchy and dependent on the author who made the map.
