Basically, before LucasArts got shut down, they were working on three projects, First Assault, 1313, and something else that was simply known as "Version Two". The footage in the link is from Version Two, and it looked very Battlefront-y, and it is not First Assault, as that didn't have vehicles.
It looked really good too :(

All I can think of is the "Imperial March" song playing and Mickey Mouse with a big cloak coming out of the shuttle into the Death Star. Get your paws off of us you damn dirty Disney!
