Fun game, but I wish it was just a tiny bit different. I know this is standard for these types of games, but I wish when merging 2 characters, they would remain those characters. This is not a deal breaker for me though, since in a way, it's fun to see what pops up after merging.

fun game so far. question, why isnt the player track for the clan pass free. also why doesn't it say that you need to purchase the pass the recent the player track rewards. it just says you need to purchase the pass for clan track rewards. and are yall planning on adding a endless coop wave mode.
