File Comment Doom Construction Kit v2.2 (Zerius Dev.) Edits DOOM, DOOM 2, and HERETIC maps. If you thought 1.0 was cool, check this out: DCK uses all the memory of your 386/486 computer to help you create intricate dungeons quickly and easily. DCK unobtrusively takes care of mundane tasks like sidedef, sector and vertex references, but still allows you complete control over the design of your map. DCK is fast, powerful, very intuitive and has a great interface. Requires DOOM 1. Last revision date in archive: 03-16-95.
