Killer Instinct Gold is a fighting game developed by Rare for the Nintendo 64. It is a sequel to the original Killer Instinct and was initially set to launch with the console in 1996 but faced delays, eventually releasing in North America in November 1996 and later in May 1997. The game features enhanced graphics and gameplay mechanics, and it was included in the Rare Replay compilation for Xbox One in 2015.
Rare was a prominent second-party developer for Nintendo, and produced the Killer Instinct series exclusively for the company as their response to Mortal Kombat. Following the success of the 1995 Killer Instinct port for the Super Nintendo home console, Rare began a sequel for the same console. They transitioned development to the Nintendo 64 upon its announcement. Gold was scheduled as a launch title for the new console but was delayed until its North American release in November 1996. It received a wider release in May 1997.
It was also included in Rare's 2015 Xbox One retrospective compilation, Rare Replay.
