Swing on over to Origin to get the Battlefront Season Pass for free. You can nab this even if you don’t own Battlefront, if you’re a digital hoarder. The pass usually costs £17.99.
The Ultimate Edition of Battlefront, which includes both the base game and the Season Pass, is only £4.16/$4.99 right now too.
EA don’t say when the offers will end, only that they’re “for a limited time only”.
