I won't bother you with words. You came here to see Admiral Ackbar in Star Wars Battlefront, and that's what you'll get. And when you're done watching the first footage of Battlefront's co-operative survival mode, why not watch more from the game, shown earlier today.
Star Wars Battlefront is scheduled for release November 17th. The PlayStation 4 version of the game will have its own timed exclusive content.
