Star Wars Battlefront 2 “offline” mode

So found a way, for steam deck at least. If you don’t have wifi at all use your mobile hotspot (no matter how crap it is) let the game have its shader cache update and then launch game. It will take a minute for it to launch however once it’s done and you’re in the menu selection screen. Turn off hotspot it will go back to ea launcher however that’s fine hit the steam button go down and you’ll see 2 options “ea app and battlefront 2” just swap and keep EA app on idk if closing it will close the game too and it repeats itself but ya
