Fighting Force 3 is a cancelled FF sequel that was in development at Core-Design for Playstation 2 and XBOX. A little tech demo from the project can be found at www.fairlyfanatic.com and a single screenshot was found on http://polygonworlds.wordpress.com. We don’t know much more on this unreleased beat ’em up, but it’s possible that it was canned because they though it would have not sold enough copies.
