Thief II is a stealth game that takes place from a first-person perspective in a three-dimensional (3D) graphical environment. The player seeks to complete mission objectives and to evade the notice of opponents such as guards. The player must minimize the visibility and audibility of the player character, Garrett, to escape detection. Players try to avoid lit areas and loud flooring in favor of shadows and quiet flooring. A light monitor on the heads-up display (HUD) indicates the player character's visibility. While it is possible for the player character to engage in direct combat, he is easily defeated.
The game's 15 missions take place in large levels that can be confronted in multiple ways. Guards may be knocked out with a blackjack or killed with a bow or sword, and their fallen bodies may be picked up and hidden. In addition to human enemies, the game features security automatons and surveillance cameras. While completing objectives such as frameups and blackmail, the player steals valuables that may be used to purchase thieving gear between missions. The player's main tools are specialized arrows, including water arrows to douse lights, moss arrows to dampen the player character's footsteps and rope arrows to reach higher ground.
Thief II is designed to be played methodically, and the player plans ahead by scouting, reading the game's map and observing patrol patterns. The player character has a zooming mechanical eye, which connects to throwable "Scouting Orb" cameras. One Scouting Orb may be deployed at a time; when it lands, the player views the game world from its perspective until normal play is resumed. The player listens for noises, such as footsteps and humming, to determine the locations of enemies. On the highest of the game's three difficulty levels, killing humans results in a game over, and in certain missions the player must not knock out any guards.
Plot
Setting and characters
Like its predecessor Thief: The Dark Project, Thief II is set in a steampunk metropolis called the City, whose appearance resembles that of both medieval and Victorian era cities. Magic and steam technology exist side by side, and three factions—the manipulative and enigmatic Keepers, the technology-focused Hammerites and the "pagan" worshippers of the Pan-like Trickster god—are in operation. Thief II takes place one year after the first game. In the aftermath of the Trickster's defeat and the failure of his plan to revert the world to a wild, primitive state, a schism in the Hammerite religion spawns the "Mechanist" sect, which fanatically values technological progress. The new inventions of the Mechanists are used by a resurgent police force to crack down on crime. The pagans are in disarray, and have been driven into the wilderness beyond the City. From there, they engage in guerrilla warfare against the Mechanists. The Keeper faction is dormant as the game begins.
The game continues the story of Garrett (voiced by Stephen Russell), the cynical master thief who defeated the Trickster. Pursuing Garrett is the new sheriff, Gorman Truart (voiced by Sam Babbitt), who has imposed a zero tolerance policy on crime. Viktoria (voiced by Terri Brosius), the former ally of the Trickster, eventually joins with Garrett to combat the Mechanists. The game's primary antagonist is the founder of the Mechanists, Father Karras (also voiced by Russell), a mentally unstable inventor who despises the natural world.
Story
The game begins as Garrett continues his life as a thief. However, he is betrayed by his fence and ambushed after an early mission, and he determines that Truart, the local sheriff, is hunting him. Keepers take Garrett to hear a prophecy about the "Metal Age", which he ignores. As Garrett leaves, one of the Keepers informs him that Truart had been hired to kill him, and he gives Garrett a letter that directs him to eavesdrop on a Mechanist meeting. There, Garrett overhears Truart and Father Karras discussing the conversion of street people into mindless "Servants", who wear masks that emit a red vapor capable of reducing themselves and nearby humans to rust. Truart promises to provide Karras with twenty victims for the Servant project, not realizing that Karras is recording his words for use in blackmail. Garrett steals the recording from a safe deposit box, in order to coerce Truart into revealing his employer.
However, Garrett finds Truart murdered at his estate. Evidence at the crime scene leads him to spy on the police officer Lt. Mosley. Garrett sees Mosley deliver a suspicious letter, which is carried through a portal by a wounded pagan. Garrett enters the portal and finds himself outside the City, and he follows the pagan's trail of blood to Viktoria, who persuades Garrett to join her against the Mechanists. On a lead from Viktoria, he infiltrates Karras' office to learn about the "Cetus Project", and inadvertently discovers that Karras is giving Servants to the City's nobles. Garrett travels to a Mechanist base to find out more about the Cetus Project, which is revealed to be a submarine. In order to locate and kidnap a high-ranking Mechanist named Brother Cavador, Garrett stows away in the vehicle.
