NBA Jam, which features two-on-two basketball, is one of the first real playable basketball arcade games and is also one of the first sports games to feature NBA-licensed teams and players, and their real digitized likenesses.
A key feature of NBA Jam is the exaggerated nature of the play – players can jump extremely high and make slam dunks that defy both human capabilities and the laws of physics.[3] There are no fouls, free throws, or violations except goaltending and 24-second violations.[3] This means the player is able to freely shove or elbow opponents out of the way. Additionally, if a player makes three baskets in a row, the character becomes "on fire" and has an unlimited turbo and increased shooting precision.[3] The "on fire" mode continues until the other team scores, or until the player who is "on fire" scores four additional consecutive baskets while "on fire".
The game is filled with Easter eggs, special features and players activated by initials or button/joystick combinations. For example, pressing A five times and right five times on any Genesis controller will activate "Super Clean Floors". This feature causes characters to fall if they run too fast or change direction too quickly. Players can also enter special codes to unlock hidden players, ranging from US President Bill Clinton to Hugo, the Charlotte Hornets mascot. On the arcade machine, there is also a hidden "tank" game that allows the player to drive a tank and shoot enemy tanks for a minute. Just before the court is shown at the start of a game, joysticks 1 and 2 must be moved down and all six of their buttons held down.
