''Perfect Dark'' is a first-person shooter video game developed by Rare for the Nintendo 64 video game console. 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.
The game features a single-player mode consisting of 17 main missions 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 traditional deathmatch settings. Technically, it is one of the most advanced games developed for the Nintendo 64, with optional high-resolution graphics and Dolby Surround Sound. A Nintendo 64 Expansion Pak is required to access the game's campaign and most of the multiplayer features.
''Perfect Dark'' was developed over the course of three years and uses a modified version of the ''GoldenEye 007'' engine. The game met with critical acclaim and commercial success upon release, selling more than three million units worldwide. Critics widely praised its customisable multiplayer modes and replay value, but opinions were mixed on its inconsistent frame rate. The game's success has led to the development of the ''Perfect Dark'' series, which includes the 2005 prequel ''Perfect Dark Zero'' and other types of merchandise such as novels and comic books. A remake, also titled ''Perfect Dark'', with enhanced graphics and online multiplayer, was exclusively released as an Xbox Live Arcade game for the Xbox 360 in 2010.
== Gameplay ==
''Perfect Dark'' is a first-person shooter in which players control Carrington Institute agent Joanna Dark through a series of levels collected together into missions.〔 The general gameplay is similar to that of its predecessor ''GoldenEye 007'', with features such as stealth sections and objectives determined by difficulty settings carried over.〔〔 Players can crouch, duck, lean, and drop from most ledges, but there is no jump ability.〔〔 A number of tutorials and training activities can be taken at the Carrington Institute, which acts as the game's central hub.〔 The Nintendo 64 Expansion Pak is needed to access the game's campaign and most of the multiplayer features, although a limited subset of the Combat Simulator options are available without the device; around 35% of the game is playable without an Expansion Pak, as estimated on the game's box and Instruction Booklet.〔
The player has access to a wide range of weapons, including handguns, rifles, submachine guns, a shotgun, rocket launchers, combat knives, grenade launchers, various explosives, and several extraterrestrial weapons.〔 Further weapons are unlocked during the training activities in the hub.〔 Almost all of the weapons in the game have two modes of fire: a primary mode in which the weapon is used in a typical fashion, and a secondary mode which uses the guns in other ways, such as them being close-quarters melee weapons.〔 Players can carry an unlimited number of weapons, and certain guns can be used in duplicate, one in each hand.〔 Most weapons have a finite magazine and must be reloaded after a certain number of shots. Interaction with objects in the environment is via a single "Use" command.〔 Enemies and players can disarm each other at close range, and the player can use this feature to steal weapons or knock foes unconscious.〔〔 Damage taken during combat for the player and enemy units is location-based, with a shot to the torso causing more damage than a shot to a limb.〔〔
In each level, the player must complete certain objectives and then exit the stage.〔 The requirements are varied, with many levels requiring the recovery and use of numerous high-tech gadgets. If Joanna is killed or fails an objective, the player must start the level again. Three distinct difficulty settings are available for each level, the choice of which will affect aspects such as the number of objectives that must be completed, enemy accuracy and damage, the effectiveness of the game's optional automatic aiming assistance, and the availability of ammunition and items such as protective shields.〔〔 If all the levels are completed on the highest difficulty, an additional setting becomes available, titled "Perfect Dark".〔 In this mode, players can customise various aspects of enemies, such as their health, their aiming accuracy and the damage they inflict.〔 In addition to the main campaign, there are four bonus missions, with three enabling the player to control other characters with unique special abilities.〔〔 Players can also unlock cheats by completing the levels within certain time limits.〔 Some cheats can alternatively be unlocked by using the ''Perfect Dark'' Game Boy Color game and Transfer Pak.〔
