I just peeked at the pass unlocks and it looks like the majority of the things you get for free without buying the premium battle pass are challenge swaps. I think every 10 or 15 levels you get a new palette or visor color but everything else is challenge swaps. It really looks like there isn’t much to work towards or look forward to unless you spend the extra money. Not sure how I feel about that. Gameplay is solid but there’s no other incentive to play. It’s fun for a few games but gets boring quick when there’s no goal to achieve other than to finish the match.
