Mario Kart 64 is the second game in Nintendo's Mario Kart series. It was first released for the Nintendo 64 (N64) in 1996, and was the second bestselling game for the N64. Mario Kart 64 rendered its levels using 3D models, while using sprites for characters, powerups and weapons, such as shells. It was the first game in the series to feature blue spiny shells, and introduced mini-turbos from power slides. It was also the first in the series to offer 4-player split-screen play.
