Universal Fighting Engine (or U.F.E.) is a tool designed to help indie developers and small companies to make their own 2.5D fighting game using a full open source framework and easy to use visual editors. Those who studied fighting games have probably realized just how complex even the smallest thing is when dealing with balance and frame data. Charts upon charts of information you just can't see while playing, not to mention the highly complex aspects of hitboxes and unique physics. That's where Universal Fighting Engine comes in. UFE provides you with an open fighting game engine ready to use, highly customizable data frame and easy to use character and move editors similar to those used by Capcom and NeatherRealm to create games like Street Fighter 4, Mortal Kombat and Ultimate Marvel vs Capcom 3.
It's really easy to use and documentation is good. The price is incredible low for what it does.
This should be hyped more. So many developers have been tinkering with 2D games for lack of technical knowhow to build this kind of framework for a 3D engine themselves, I'm sure it would take off like crazy if people just knew it was out there. People who aren't already working on other Unity engine projects, that is.
