A set of 12 UDMF single player levels. They start off relatively simple and straightforward but become progressively more complex and ambitious. Requires GZDoom. Levels take place in a variety of settings, alternating between Earth/techbase and Hell. Map design is mostly non-linear, with different paths that can be tackled in any order, although this varies by level. The WAD as a whole is probably slightly on the easier side, however, there are two special extra difficulty levels (Insane and Hellish) for those seeking a greater challenge. Pistol start is enforced for every level, and jumping/crouching is disabled. Freelook is strongly recommended, although not strictly necessary. Mostly vanilla-style gameplay although utilises certain modern features such as 3d floors, slopes, wormhole portals, and custom monsters.
