We've seen Walker Assault and Survival in action already, thanks to their reveals at E3.Walker Assault comes is a riff on the opening Hoth battle in Empire Strikes Back, and features various sorts of ground and air units battling to take control of/escape from the rocky ball of ice. The map, and the beta, will also let players do battle as either Luke Skywalker or Darth Vader, two of the hero/villain characters that will appear in the game.
Survival is a bit simpler: You and a fellow Rebel trooper are stranded on Tattoine—because it's always Tattoine, isn't it?—and must fight off increasingly difficult waves of Imperial forces, until they decide that you're too hot to handle and bugger off to do other things, like enforce the subclauses of an unfair trade agreement. Because who doesn't want to watch that, right George?
The beta will also see the launch of the Star Wars Battlefront Companion, a mobile app for iOS and Android that will feature the strategy card game Base Command and enable players to check their stats and progression, communicate with friends, and earn in-game credits used to unlock Star Cards, weapons, and other resources and assets.
EA hasn't revealed when the beta will take place any more precisely than "early October," nor has it said if it will be open or closed, or how you'll go about gaining access if it's the latter. You will have to use Origin to play the game, however, which shouldn't come as any surprise but is worth clarifying anyway, just in case.
