Hypercharged: Unboxed is an arena wave-based tower-defense multi-player game. The theme? Toys!
Battle all kinds of house toys from robots to bouncing balls and defend your hyper cores. The demo is single-player but the full game has multi-player where you can defend your bases against and with your friends. Upgrade your characters weapons and abilities, then go out there and slay those TOYS!

Proton was able to handle the demo perfectly on my GeForce GTX 1060. This is an Unreal Engine game and hopefully there will be a Linux port planned in the future... until then, play in Steam with Proton.
