Hi,
our servers are live again! We were able to find the cause for the problem we had. In order to avoid further issues, we ask you to restart your Steam client and to verify the integrity of the game files, which only takes a few moments.
You can find the option to do so by right-clicking on RockShot in your library > Properties > Local Files > Choose "Verify Integrity of game files"
Thank you for your patience!
The RockShot-Team
