Can I Run Rebel Galaxy?
Double Damage Games released Rebel Galaxy in 2015. It is an action adventure game, self published by the studio. It offers a single player campaign. With more than 7 thousand player reviews on Steam, its behaviour on real hardware is well documented. A gamepad works without remapping, since controller support is complete. Saves sync through Steam Cloud, so moving between machines does not cost progress. There are 37 achievements to chase. 7 languages are covered by the store listing. It is not Windows only, with macOS covered too. Being over ten years old, its ceiling was set by the hardware of a different era. Critics scored it 75 on Metacritic.
