Re: how do i get chewbacca

@TheBlack006 Hi, Chewbacca is part of the Death Star Expansion pack for the game.

If you have this pack, your son can play the hero-based modes of the game to choose him, or they can get to play him in regular matches by playing the Death Star maps and picking up a hero token. 

Thanks for the post.
