Thankfully LucasArts and Raven Software released the source code for Jedi Knight - Jedi Academy letting modders have the power to do some pretty amazing things with an already great base game. And already people have been re-exploring the game with some interesting results.
One of the most interesting mods to come from the generosity of Raven Software is Jedi Fighter, a mod that transforms the game into something that plays homage to some of the more classic fighting games, like Street Fighter II. It's a battle of good versus evil, with five different locations from a TIE hanger bay to Hoth and more. They've added in 10 characters from the expanded universe, ones that might be familiar. And of course it has the obligatory dynamic camera so you can have a cinematic view of the action.
It's the Star Wars fighting game we've been waiting for, the one we never knew we really wanted. It's fast paced and looks quite nice actually. In order to play the mod, you'll have to download the OpenJK engine to get it to work.
Right now it's just a work in progress, but it's scheduled to be completed around June. They also welcome input and contributions from the community. I can see this becoming the next eSports game.
