Doom is a popular first person shooter video game. Released initially in late 1993 for DOS, it quickly became ported to more consoles than you or your grandpa could shake a stick at!
The source code for the game's engine, the Doom engine, was released publicly in 1997. Thanks to this, there have been several different projects that have added more functionality to the Doom engine. A popular example of this is ZDoom.
The PC versions have all game data contained in a single file, the WAD file. There are two types of WADs: PWADs and IWADs. IWADs are WAD of the original commercial games released for the Doom engine, such as Doom, Doom II, Hexen, and Heretic. PWADs are WADs made by hobbyists (and BotBrs here) that use graphics and sounds from an IWAD. The most used IWAD for Doom custom Doom levels is Doom II's.
