Prototype (stylized as [PROTOTYPE]) is a 2009 action-adventure video game developed by Radical Entertainment and published by Activision. It was released in June 2009 for the PlayStation 3, Xbox 360, and Microsoft Windows. In July 2015, the game was re-released alongside its sequel as the Prototype Biohazard Bundle for the PlayStation 4 and Xbox One. Separate versions of the two games became available in August 2015. In Prototype, players control an amnesiac shapeshifter named Alex Mercer as he attempts to stop an outbreak of a virus called Blacklight in Manhattan, which mutates individuals into powerful, violent monsters. Alex also attempts to uncover his mysterious past while coming into conflict with both the US military and a black operations force called Blackwatch. Outside of the main story, players can freely explore the game's open world and engage in several different side activities. The game was well received by critics following its release, gaining praise for its originality, storytelling, and engaging gameplay, while being criticized for its control scheme and scenery. Several reviewers compared and contrasted it with Infamous, a game released one month prior which had many elements similar to Prototype. It was also a commercial success, selling 2.1 million copies by March 2012. A tie-in comic book miniseries, which serves as a prequel to the events of the game, was published by DC Comics. A sequel, Prototype 2, was released in April 2012. Gameplay Prototype is an action-adventure game played from a third-person perspective and set in an open world based on modern-day Manhattan. The game's setting remains mostly faithful to the real city and includes all of its famous landmarks, including the Empire State Building, the Chrysler Building, 40 Wall Street, 28 Liberty Street, the Conde Nast Building, the Metlife Building, One New York Plaza, and the New York Life Building, among others. The player character, Alex Mercer, has the ability to shapeshift, allowing him to change his body to resemble anyone. His powers also play into the game's combat system, as Alex can "consume" others to regain health, absorbing their biomass entirely. This also allows him to take on the forms of the human enemies he absorbs, thereby allowing the player to move about the enemy as one of them. The disguise will only last as long as Alex remains inconspicuous. Alex also possesses superhuman strength, and will kill most humans with a single punch. He can perform
