Electronic Arts unveiled its plans for sweeping changes to Star Wars: Battlefront 2 last week, including an overhaul to the progression system that removes Star Cards from crates, a return of the Crystals currency, and limits on what you can buy with them—which is to say, cosmetic items only. The update went live today, revealing that it's also unlocked all hero characters and ships: No more having to grind your face off for credits before you can start chopping people to bits as Darth Vader. 

Under the new system, hero characters and ships will earn experience points and levels through gameplay. Each new level grants a skill point point that can be used to unlock or upgrade character-boosting Star Cards. "With all characters now having a Unit Level, we don’t want to limit anyone’s chance to progress as we change the way you interact with these characters," EA community manager Sledgehammer70 wrote.
