Star Wars Battlefront 2 won't arrive for another week, but Electronic Arts has already unveiled what players have to look forward to in a free update coming in December. Beginning on December 5, players will have the opportunity to sign up for either the First Order or the Resistance, which will lead into faction-based challenges with "special rewards."

Following that, on December 13, Finn and Captain Phasma will become available for purchase with in-game credits. Costs haven't been confirmed yet, but based on what we've seen in the Play First trial of the game, new Hero characters range in price from 20,000 to 60,000 credits.
