Hellscape is a 10-level Boom-compatible episode-reinterpretation of the original Doom II Hell levels, made by Christopher Lutz. It features long-sprawling levels with both tricky and intense combat, bolstered by the signature exquisite visuals from Chris. Screenshots provided aren't sufficient to depict them justly.
