Battle Tennis is a part-tennis and part-fighting parody. It's a cartoony arcade game with fast action and simple controls. Players are armed with special defensive and offensive moves and powers to defeat their opponents in battle. The game uses a completely 3D environment with a very unique art style, which was inspired, instead of limited by, video game requirements. Each round develops as a regular tennis game, using the same scoring and most rules, although some are tweaked to make the game faster.
