The CD contains twenty [[WAD]] files created by various authors under contract. The file teeth.wad contains a secret level, so there are a total of 21 levels. To ease playing these WADs, the collection also includes Doom-It, an application created by Chris Badger for id Software which allows the individual WADs to be loaded through a menu interface.

== Native support ==

Recent versions of the [[Eternity Engine]] include native support for playing the Master Levels from within Doom 2 without use of [[parameter|command-line parameters]] or the need to exit the game to play other maps or the normal game. After configuring the directory in which the maps are stored, the menu pictured to the right can be used to start any of the maps. The secret level of TEETH.WAD is accessible by using the secret exit switch in the first map of that WAD file. After a level is completed, the menu reappears. A new map can be started, or escape can be pressed to return to the Doom 2 title screen.
