Lethal League

In Lethal League, up to four players face off against each other in an arena. The goal is to hit a baseball back and forth, and have the ball hit other players until there's only one player left. With each consecutive hit, the ball will speed up more, making it harder for the other players to not get hit and hit the ball back.
