About

The Doomsday Engine is a portable version of the classic first person shooters DOOM, Heretic, and Hexen. It lets you enjoy the original games using modern technology, including high-resolution OpenGL graphics, 3D models, and dynamic lighting effects.

Data files from the original games are not included; you must acquire a copy of the original games from id Software and/or Raven Software. You may also use free alternatives such as https://freedoom.github.io/.
