How cool that you downloaded the rumble club. You should try some battles with me to see if you play well, hahaha. Just kidding.
There are some special events where you can team up with other players, although last time I saw they were no longer available.
This game, after Stumble guys, is one of my big favorites.
It's the best and in the short time I've been playing it, the fun doesn't stop and those punches are dangerous.
