freedoom
Replacement game files for Doom game engines
Though the Doom engine source code is libre, the original game data (graphics, maps, etc.) is not. Freedoom is an alternate game data set that can be used with a Doom engine, such as prboom-plus, chocolate-doom or gzdoom, to form a free Doom-based game.
