context_page_description: Doom WAD is the default format of package files for the video game Doom and its sequel Doom II: Hell on Earth, that contain sprites, levels, and game data. WAD stands for Where's All the Data? Immediately after its release in 1993, Doom attracted a sizeable following of players who created their own mods for WAD files—packages containing levels, graphics, and other game data—and played a vital part in spawning the mod-making culture which is now commonplace for first-person shooter games. Thousands of WADs have been created for Doom, ranging from single custom levels to full original games; most of these can be freely downloaded over the Internet. Several WADs have also been released commercially, and for some people the WAD-making hobby became a gateway to a professional career as a level designer.
  There are two types of WADs: IWADs and PWADs. IWADs contain the data necessary to load the game, while PWADs contain additional data, such as new character sprites, as necessary for custom levels.
context_section_description: Freedoom is a project aiming to create a free replacement (modified BSD License) for the set of graphics, music, sound effects, and levels (and miscellaneous other resources) used by Doom. Since the Doom engine is free software, it can be distributed along with the new resources, in effect providing a full game that is free. Freedoom also allows users to play any of the thousands of other WADs that normally require the original game.
  The project distributes three IWAD files: the two single-player campaigns named Freedoom: Phase 1 and Freedoom: Phase 2, and FreeDM, which contains a collection of deathmatch levels.
  Freedoom does not require any source port to run, and can run on any limit-removing source port of Doom.  It can be downloaded from its homepage, https://freedoom.github.io/
  A similar project, Blasphemer, aims to create a complete free version of Heretic, but is less fully developed than Freedoom.
