About Star Fox 64

The update to the 16-bit Super NES title continues the original's on-rails 3D shooting action on the Nintendo 64. Starring Fox McCloud, Peppy Hare, Falco Lombardi, and Slippy Toad, this new 64-bit version contains 15 plus levels, easy, medium, and difficult paths, forward-scrolling levels as well as full 3D realms, and a three-part multiplayer mode using a four-player split screen. In addition to plenty of Arwing action, the game introduces a new hover tank and even features a submarine level. The 8-megabyte cartridge also boasts voice samples from 23 different characters instead of the original's animal noises. Star Fox 64 was the first game to feature Rumble Pak support. A Rumble Pak bundle and standalone version of the game were sold. Released in Europe under the name Lylat Wars.
