At Star Wars Battlefront a beta for PC, Xbox One, and PlayStation 4 will be available at the beginning of October. It will also have an offline mode.
In a large community post from Star Wars Battlefront, a single new piece of information about the upcoming beta was provided: Once downloaded, players will be able to play the “Survival Missions”, one of three modes, offline. On consoles, this can also be done in the so-called couch co-op mode, in split-screen.
There is currently no more information. Everything else that was mentioned was already known at the announcement of the beta: three missions, open to all, players will only need to register, and so on.
When exactly it starts, EA hasn’t said yet. Just: Keep your eyes peeled.
