1x1 is an MBF21 (-complevel 21) community project hosted in my discord server. The concept is simple: the maps only use 1 texture and 1 flat, with the exception of a single switch texture and F_SKY (which was only allowed to be used if the texture was transferred to it!). The wad features 24 mbf21-compatible maps (01-21, 31-33) made by various authors, with difficulty ranging from around early Sunlust difficulty to absolutely batshit crazy, though difficulty settings are implemented. Maps are ordered very roughly by difficulty. Pistol starts are intended but not required.
