An update named NBA Jam Tournament Edition (commonly referred to as NBA Jam T.E.) was released in arcades. NBA Jam T.E. included updated rosters, new features and Easter eggs combined with the same gameplay of the original. Jon Hey created new music specifically for NBA Jam: T.E. to replace the original NBA Jam music. Teams now consisted of three players (though only two could be on the court at any time; in practice, the extra player meant greater variety in lineups), with the exception of the new "Rookies" team, which consists of five players, all picked in the 1994 NBA draft. Players could be substituted into the game between quarters. The game also featured new hidden teams and secret playable characters. Early versions of the game included characters from Midway's Mortal Kombat games.[4] Players were also assigned more attributes, including clutch and fatigue levels. In addition, the game also introduced features such as a "Tournament" mode that turned off computer assistance and on-court hot spots that allowed for additional points or special slam dunks.
