Perfect Dark is a 2010 first-person shooter developed by 4J Studios and published by Microsoft Game Studios for the Xbox 360 through its Xbox Live Arcade download service. The game is a remaster of the original Perfect Dark, which was released for the Nintendo 64 in 2000. Although the gameplay remains largely unchanged, the remaster features significant technical improvements over the original, including new higher-resolution textures and character models, a higher frame rate, and a multiplayer mode that supports the Xbox Live online service. The story of the game follows Joanna Dark, an agent of the Carrington Institute organization, as she attempts to stop a conspiracy by rival corporation dataDyne. Perfect Dark was developed over a course of nearly a year and its game engine was completely re-written from scratch to support several Xbox 360 features. Therefore, although the game plays exactly the same as the original, the code and renderer is different. The game received generally favorable reviews. Some critics considered the relatively unchanged game to be outdated, but most agreed that the title was a solid revival of a classic. As of the end of 2011, the game had sold nearly 410,000 units. In 2015, the game was included in the Rare Replay video game compilation for Xbox One. Gameplay Perfect Dark is a remastered release of the 2000 first-person shooter video game of the same name, which was developed by Rare and released for the Nintendo 64 as a spiritual successor to the 1997 hit GoldenEye 007. The game features a single-player mode consisting of 17 levels in which the player assumes the role of Carrington Institute agent Joanna Dark as she attempts to stop a conspiracy by rival corporation dataDyne. It also features a range of multiplayer options, including a co-operative mode and a "Combat Simulator" where numerous players can compete against each other in traditional deathmatch settings. Combat Simulator matches can be highly customised and can include bots. A "Counter-Operative" mode, where one player controls the protagonist while the other controls enemies throughout a single-player level, attempting to stop the first player from completing objectives, is also included in the game. The remaster changes little from the core gameplay of the original game, but offers several enhancements in the multiplayer department. In the remaster, any of the multiplayer modes can be played in either splitscreen or through the Xbox Live online service. An online leaderboard
