Overview - MFG Thread Link

If you are upgrading from an older version of M.U.G.E.N, please read the Upgrade Notes.

M.U.G.E.N is a 2D fighting game engine that is enables you to create commercial-quality fighting games. Almost everything can be customized, from individual characters to stages, as well as the look and feel of the game.

After downloading M.U.G.E.N, unzip it into a new folder and double-click mugen.exe to run.

The majority of content created for M.U.G.E.N tend to be distributed as individual characters, stages or motifs. Assembling a game is as simple as downloading the content of your choice, and configuring M.U.G.E.N to know about it.

M.U.G.E.N is designed to be used by people with little or no programming experience, but with some artistic talent and patience to learn. Of course, having some programming background does give you a bit of a headstart. However, if you are just looking to play with downloaded content, all you need to know is how to unzip files and edit a text file.

Here's a sampling of features you can find in M.U.G.E.N:

• Customizable title screen, character select screen, life and bars, game sound effects, fonts and more.
• Characters can have any number of sounds and sprites of any size limited by your computer's memory.
• Choose from multiple resolutions, ranging from 320x240 up to full HD at 1920x1080.
• Cutscenes.

Game Engine

• Use up to 7 buttons for a character.
• Regular moves, special moves, super moves, etc.
• Projectiles and special effects.
• Move cancels and combos, multi-part moves and throws.
• What your character can do is defined by a scripting language (and your imagination).

M.U.G.E.N is free for non-commercial use. If you have other needs, just ask us. You can read the full license text in the README file.
