SpaceBlast.io is another fun-addicting multiplayer online IO game. Choose a nickname, customize your ship and move through grid-space taking out other players' spaceships. You should think about levelling up first and use up-grades, otherwise you won't stand a chance to survive that bullet hell. For this, you have to blow up asteroids, but don't stand too close of them or you might get hit by explosions. So try to get your name to the top of the scoreboard and try to complete achievements. Have fun with SpaceBlastio!
