Overview

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.
