Hello brave astronauts,
We are excited to announce a new Steam Playtest for Cosmic Carnage is just around the corner! The cosmos is a dangerous place, and we need your help to clear out the final bugs, balance the weaponry, and ensure smooth hyperspace travel before our official launch.
This is your chance to get an early look at a late stage build of the game and help us identify those last minute anomalies.
