It is considered the spiritual successor to Rare's earlier first-person shooter GoldenEye 007, with which it shares many gameplay features. Perfect Dark was first released in North America on 22 May 2000; PAL and NTSC-J releases followed soon afterwards. A separate Game Boy Color game, also titled Perfect Dark, was released in August 2000 as a supplement to the game and allows certain features within the Nintendo 64 game to alternatively be unlocked via a Transfer Pak.
