My little brothers and I got a PS4 this Christmas with that Battlefront bundle. If you press Multiplayer, the next screen will inform you about PS+. However, there’s an option on that same screen to select a 2 day trial without inputing any information, such as credit card. It’s literally hop in and play for those two days. We just finished that two day trial and had quite a lot of fun but yeah, it’s a huge bummer of how much of this game is a cash grab if not playing on PC.
And sadly yes, a bulk of content is online only.
