Memento Mori

Memento Mori is a 1995 megawad that contains 32 new levels, designed by two members of the Innocent Crew, Denis and Thomas Möller, along with 19 other authors, including Tom Mustaine and both Dario and Milo Casali. In contrast to most megawads, it is designed especially for cooperative multiplayer gameplay, although it can be played in single-player as well. It is also one of the few PWADs that are allowed to be used in Compet-N speedruns. The soundtrack was composed by Mark Klem, who also designed one level and co-designed another.

A sequel, Memento Mori II, was later developed and released a year later.
