Based on the movie of the same name, Space Jam centres around an invasion of Looney Tunes land by tiny aliens. The fate of the Tunes is to be decided by a basketball game, and for this the aliens turn into the huge, evil Monstars.
The gameplay is mostly about simulating basketball matches with two-on-two or three-on-three teams. You can play as either the Monstars or the Looney Tunes who have the help of Michael Jordan. The games come with various minigames that fill in the gaps and provide upgrades to your character's abilities on the court.
Minigames include finding MJ's basketball togs, a space race, and other challenges that require teamwork between players from both teams. There are around five minigames in total, each adding a new skill or advantage to your gameplay.
The multiplayer mode is a key feature of the game. You can play against another player in a traditional one-on-one match, team up with friends as part of a co-operative mode for two or three players, or even compete in a three-on-three game using multitaps.
Players can choose from 12 Looney Tunes characters and five Monstars to join their team. Each character has its own set of statistics: Speed, Shooting, Rebounds, and stamina.
The gameplay is designed for fast-paced action with an arcade feel, featuring a series of five matches in a row without any real progression system due to the lack of memory card support.
