A new update for Star Wars Battlefront 2 has addressed some of the game's multiplayer concerns. The most notable change patches the Squad System, but the update addresses a few other concerns and also adds new content.

If you're playing with a group of friends, you will be automatically placed in a squad together. The new Squad System promises to load you back into your group more quickly after your soldier is killed. Upon death, you will be able to toggle between all your surviving squad members to decide who you want to respawn on. If you're playing solo, you'll just be thrown into a random squad, but you'll still be able to choose who you spawn on between each death. The new Squad System also allows you and a friend to play in private two vs. two Hero Showdown matches.
