Maximum Doom

Maximum Doom is the name given to bonus content distributed with the Master Levels for Doom II in 1995. It consists of 1830 amateur PWAD files of varying quality downloaded from the Internet (191 for Doom, 1629 for Doom II and 10 for Heretic). Many of these files are still available, for example at Doomworld. Some contain copyrighted material, such as sound files from television programmes such as Monty Python's Flying Circus and The Simpsons. These files are still available at.

In all, Maximum Doom had close to 3,000 levels.
