Apocalypse is a set of 16 CDoom maps by Carlos Guariglia, designed to be extremely hard. The levels feature a lava theme, many Cyberdemons, 3D floors and an excessive difficulty level.

The story of the WAD is that Jesus returned to Earth and took all people that believed in him to Heaven (the Rapture). The player assumes the role of an unbeliever that stayed on Earth and must fight angels that rebelled against Jesus.
