The footage, which you can watch in full below, features Anakin Skywalker and Darth Maul going at it with lightsabers, hacking away and using the force for throws until one of them is able to skewer the other.
As the description on the video says, the footage is fairly "repetitive," but it was simply designed to show off all of the potential moves a game like this could make. There was a presentation paired with the video as well, and Tsui says it was part of a pitch for a new game back when he was working at Studio Gigante in Chicago. We'd say his team might want to return to the idea for the upcoming Star Wars: Episode VII, but perhaps it's better if the Jedi knights stay away from fighting games in general.
