Alleged concept art for the cancelled Star Wars battlefront game which was supposed to take place in an alternate universe.
"Star Wars Battlefront IV was supposed to take the Star Wars storyline into a different direction, with a perfect "what-if" scenario where the tides were turned. This means the characters you see in 1-6 were flipped, such as Kenobi becoming a sith lord, or Anakin not losing his limbs on Mustafar. Some parts of the story went as far as Anakin killing Yoda in a duel at Naboo. Along with that, Battlefront IV featured larger battles than any other Battlefront before. This meant a large portion of the planet was playable on, and boosting its player count into tremendous amounts during matches. This was truly going to be the largest Star Wars game ever made."
