M.U.G.E.N (also known simply as MUGEN) is a freeware 2D fighting game engine designed by Elecbyte . Content is created by the community, and thousands of fighters, both original and from popular fiction, have been created. It is written in C and originally used the Allegro library. The latest versions of the engine now use the SDL library.
The engine uses 4 directional keys along with 7 buttons for gameplay (A, B, C, X, Y, Z and Start), in order to accommodate six-button fighters which use three punches, three kicks and a start button. However, characters do not necessarily use all seven buttons, nor need to follow a traditional six- or four-button format.
At most, two players can control characters, with others being controlled by the engine's AI (including Watch Mode, a demo mode where the computer controls all characters). In addition, several gameplay modes are available via the main menu.
