The Wii U gamepad serves as a action screen, where it shows actions like jump, roll, glide, and force blast. He can collect multiple lightsaber crystals, like purple, green, blue, yellow, and even orange. Starkiller does in fact have two lightsabers again, along with a double sided one he gets later in the game. Instead of always fighting on the ground, there are new air battles where Starkiller flies in his new ship, Sencicus lll.
The gameplay would be nothing like the first two games. After using the force to find his way through, he comes across a species of the planet, who were stuck on the planet because of a giant monster that uses the force. He crash lands on a strange planet and is desperate to get help. After Starkiller leaves Coruscant, he goes out to find Kota, but is attacked by an unknown enemy. Starkiller wakes up with two artificial arms, a breathing mask and a oxygen pipe. After the medical droid examines him, they find his lightsabers and know he's a Jedi. After they find it on a search for a meeting base, the troopers take the body back to Coruscant to be reborn. The now dead Starkillers body lies in a pile of garbage on the Kamino Cloning Facility, left to be found by the Rebel Troopers.
The New Jedi Order has been rebuilt, with Master Luke Skywalker running the Jedi Temple in Coruscant. It has been 2 years since the death of Emperor Palpatine and Darth Vader.
