which can be used to temporarily stun a target. This does minimal damage, but it does allow the player to seize the stunned enemy's weapon. However, after each use, the taser must recharge before it can be used again, meaning it cannot be used as a regular substitute for the game's melee weapons. Irrespective of whether the player is carrying a firearm or a melee weapon, only one weapon can be carried at a time. The other primary game mechanic is forensic crime scene investigation. The game utilises a context-sensitive button, which can call upon a suite of tools to find and record evidence. When the player encounters an "Instinct Area", the game will alert them to the presence of evidence. Pressing the tool button will automatically deploy the correct detection tool needed to locate the evidence. Once the evidence has been located, pressing the tool button again will automatically ready the necessary collection tool. Once collected, the evidence is automatically sent to the lab to be analysed. Detection tools include a UV light, a laser light, and a spectrometer. Collection tools include a sampler, a portable 3D scanner, and a digital camera. Examples of evidence include fingerprints, footprints, fibers, residues, particles, and blood splatter. Plot Ethan Thomas is an FBI agent assigned to the Serial Crime Unit (SCU) in the fictional city of Metro. Possessing the ability to sense a killer's actions, Thomas has the highest solve rate in the unit. However, many of his recent cases have gone cold. Meanwhile, he is convinced that the recent rise in serial killers is connected to a spike in crime, specifically assault amongst vagrants. Arriving at the location of a homicide in a derelict building, Thomas is met by Det. Dickensen and Ofc. Becker of Metro PD. They conclude that the murder is the work of the "Match Maker", a killer that uses mannequins in his crimes. Realizing that someone else is in the building, they split up, but when Thomas loses his gun, a man takes it and holds him at gunpoint, saying, "we are both on the same path of righteousness." He then shoots and kills both Dickensen and Becker before pushing Thomas through a window. Thomas wakes up in his apartment to find Malcolm Vanhorn, a family friend. Vanhorn warns Thomas that he is wanted for the deaths of the police and advises him to run. Assisted via
