Nearly an hour of Star Wars: Battlefront 3 gameplay footage has been posted online.

The video gives the most lengthy look yet at the now-cancelled shooter from TimeSplitters developer Free Radical Design.

Levels featuring Cloud City, Tatooine and the Death Star are included in the gameplay, posted online by regular leak site Past to Present.

Missions include simple firefights, assaults on specific targets, and even speeder bike racing. The game's much touted surface-to-space technology is also shown off.

The game appears to be in a rough pre-alpha state, as shown in previous leaks from the binned Battlefront 3 project.

Free Radical was working on Star Wars: Battlefront 3 and 4 before LucasArts pulled the plug on the projects, the studio's co-founder Steve Ellis told Eurogamer earlier this year.

More than two years of work had gone into Battlefront 3 by this point, although the footage leaked so far comes from a much earlier build.
