Rock Bottom is currently in beta stage. What that means in this case is that the game is still far from done, but the features and changes that are implemented get tested by a small group of people, the testing team.

If you want to be a part of that testing team, the only way to currently become a tester is to check out Ellpeck’s Patreon page and get one of the “RB” rewards.
If you do decide to become a patron: Thanks so much!
