Dark Rift (Space Dynamites in Japan) is a 3D fighting video game for the N64, notable for being the first N64 game to use 60 fps, as well as being N64's first native fighting game. It is also unusual among fighting games in that fights go for a default three-out-of-five rounds, as opposed to the more conventional two-out-of-three.It was originally conceived as Criticom II, and is the second of three fighting games developed by Kronos Digital, falling between Criticom and Cardinal Syn.
