Master Levels for Doom II 25th Anniversary MIDI Pack

Master Levels for Doom II 25th Anniversary MIDI Pack is a music pack for Master Levels for Doom II created by Peter Lawrence (MegaSphere) along with several other musicians. To make it compatible with the MIDI pack, user must compile all Master Levels WAD files into a single WAD file using a such as SLADE 3, and make the order of the maps the same as the PSN's Master Levels.

The project was first announced in the Doomworld forums on December 24, 2020, to celebrate Master Levels' 25th anniversary which occurred two days later, and the final version was released on January 18, 2021.
