Comment: From the readme: "A pseudo-reimagining of Doom I Episode 3: Inferno, except in the Doom II universe. Includes map contributions from the incredible level designers Peerdolius, Phobus, and SuperCupcakeTactics. Jumping and crouching are highly discouraged, as they can break the levels, and to be honest freelook is also discouraged as well, as this is meant to be an old-school Doom experience."
