Uchu.io

Uchu.io is a multiplayer arena game where you have to build and design your battleship. The game starts off with a small and simple ship, but you can modify and upgrade it with thrusters, reactors, cannons and more. In order to make these modifications, you will have to mine asteroids and fight other players to reach new levels of the game. The FFA mode in the game allows you to buy stronger ships with the minerals you gain during a fight. There is also a coop mode where you can customize your own ship.
