This Lucas-baiting moddery from a team of German chaps aims to recreate Star Warsian combat in Call of Duty 4: Modern Warfare. Are Lucasarts still litigious about this kind of thing, or have they eased up nowadays? It does very much look like COD4 with Storm Trooper and Rebel skins, although the Tatooine setting positively scream's Counter-Strike's Dust. But it's got the pew-pew lasers and the epic music, so it's going to make a fair few gentlemen very happy, I don't doubt. Galactic Warfare's trailer can be found in a galaxy far, far away. Also, below.
More details here, but in German alas. Fortunately, it does have pictures.
