In 2006, LucasArts decided to cancel the Star Wars game that developer Free Radical was working on, that game was Star Wars Battlefront 3. The cancellation left us with plenty of leaked videos showing off gameplay, reminding us of the game that could have been.
YouTuber FuZaH has uploaded two videos showcasing the game's training missions as it was in 2008, post-cancellation in its Alpha state. The first gameplay video shows off the first half of the training mission, which has X1 and X2's voices switching between two people. The second video offers a look at the second half of the mission.

Fans attempted to bring the game back to like in an Unreal Engine 4 remake called Galaxy in Turmoil, but that game was hit with a cease and desist from EA and LucasFilm. Luckily, the developers can move forward with the game… but only if they remove all the Star Wars stuff.
