What is it: at its core, Hyper Gunsport is a cooperatively competitive action game where the object is to shoot the ball into goals of varying difficulty, while the opposing team tries to do the same. Each time the ball crosses the net its point value goes up, so longer volleys mean bigger points and higher stakes.
Hyper Gunsport is basically an upgraded version of what the older Stadia exclusive was, the developers say "Hyper Gunsport is the sequel to the original Gunsport in the sense that Super Street Fighter II Turbo is the sequel to Street Fighter II".
Now, they've actually packaged up Gunsport itself into a Beta version you can try out on Steam, with some Stadia bits stripped out of it. As they said on Twitter: "Stadia is shutting down tomorrow. This means all exclusives, like the original Gunsport, will blink out of existence. But!! Since we care about game preservation we've made an offline version of Gunsport available in the Steam version of Hyper Gunsport, through the beta channel.", and they continued, "Anyone who bought Hyper Gunsport on Steam already has access to this if they want to compare and see the differences. It's offline, and has the Stadia trappings stripped out, but at least it exists! Select the beta and type OriginalGunsport to unlock it.".
Along with the Native Linux support, it's also Steam Deck Verified.
