You thought carnage.wad was hard, well this new one makes it look easy. Not only is it much harder, but it is HUGE. It is nine levels covering the entire Dome of D'Sparil episode. You will be able to finish the level without having to find any secrets, although some areas will seem like they are. To kill all the enemies (especially the Chaos Serpents), you will have to find all, if not most, of the secrets.
Doom, ROTT, Nintendo, and SquareSoft for the music Doom and Hexen for a couple of textures Hexen for a few sprites
Level one has the entire level 1 of carnage.wad in it.
All other levels are original.
