A beta build of Free Radical's Star Wars: Battlefront 3, cancelled during development due to concerns around budget, has been shown via a video captured and shared by Past to Present Online.
The hour-long demo consists mostly of third-person combat on the Cloud City/Bespin map, demonstrating both the firefights on foot and in the air (X-wing combat). He also shows the special character mode: something presented in Battlefront 2 where you had the chance to play one of the more significant characters from the movies (in the demo he shows Boba Fett and Luke Skywalker).
As this is (was) an early build of the game, there are some technical hiccups. Particularly the screen tearing and frame rate dropping into single figures; but this is what you'll get before optimisation. And if you look past the technical misappropriations, you see a game in which players could traverse a huge map either on-foot or by vehicle, with seamless transitions.
Seeing this now, the concepts of an unfinished product, makes us think the simple question: "what if?" Take a look. It's an hour long; but it's more than worth seeing Free Radical's talent applied to the Star Wars universe.
