Prototype (stylized as [PROTOTYPE]) is an action-adventure open world video game developed
by Radical Entertainment and published by Activision. The game was released in North America on June 9, 2009, and in southwestern parts of North America as well as Oceania on June 10, and was released in Europe on June 12.
The game is set in New York City, where a virulent plague known as Blacklight is spreading through Manhattan. Those infected are mutated into hideousmonsters of varying form, with an uncontrollable rage to kill all uninfected life-forms and a military black operations force called Blackwatch has been deployed to keep the infection from spreading. At the center of it is theprotagonist, Alex Mercer, an incredibly powerful shapeshifter with no memory of his past. Parallel to the game's storyline is the ability to play the game as a sandbox-style video game giving the player freedom to roam Manhattan.
Alex's primary superpower is his ability to shapeshift, changing his body into anyone. Going hand-in-hand with this power is his ability to "consume" others, absorbing them entirely. This process allows Alex to quickly regain health by absorbing the biomass of his enemies. This also allows him to take on the forms of the 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 has incredible physical strength, and will kill most humans in a single punch. He can perform various melee attacks without shapeshifting, as well as more gymnastic moves such as air combos, sliding along the ground using any humanoid enemy's body, and a high-speed rolling cannonball attack.
Alex can also transform parts of his body into a selection of martial implements acquired over the course of the game, either as purchased upgrades or being given them. Offensive powers include the large and powerful Blade arm, fast razor-sharp Claws (which can also erupt large spikes from the ground), the telescoping Whipfist, Musclemass that augments his strength, and the slow but powerful Hammerfists. Defensive options consist of a large shield on Alex's left arm for blocking ballistic attacks that needs to regenerate after excessive damage, and full body armor that exchanges agility and speed for toughness in hand-to-hand combat; both will allow Alex to plow through most obstacles when active. Vision modes include thermal vision, which allows Alex to see enemies through smoke and other obstacles at the expense of a decreased vision range, and Infected vision, which highlights those infected with the BLACKLIGHT virus as well as military units. Both vision modes muffle all of Alex's other senses, such as hearing, in order to concentrate on his sight. One defensive and offensive power may be active at a time, and using either will negate Alex's current disguise. In addition to his own abilities, Alex can take the weapons from defeated or absorbed enemies. These include automatic rifles, machine guns, grenade launchers and missile launchers. He can also seize control of military vehicles, such as tanks and helicopters.
Alex's most powerful attacks are the Devastators, which require Alex to be in Critical Mass- either a state of near-death or the exact opposite, having excess stored biomass and increased health. These include the Tendril Barrage, which fires impaling tendrils from his body in all directions, the Groundspike Graveyard, which erupts massive spikes from the ground all around Alex, and the Critical Pain, which fires a single beam of hardened biomass from his hands to severely damage a single target.
For movement around the city, Alex uses his increased physical abilities. When sprinting, he will automatically hop over cars, barriers and other obstacles without losing momentum. Alex will also scale any wall he comes into contact with and simply knock aside any humanoids that get in his way without stopping. He can jump great heights and distances, enough to clear five-story buildings, and can sprint at extreme speed indefinitely. Falls cause no damage to the player even from the greatest heights. Even small jumps are enough for Alex to dent the ground beneath him, and falls from sufficient heights will create shockwaves at the point of impact which will kill most humans nearby and send objects as large as cars flying. Falling height also factors into several of Alex's melee attacks.
Enemies in the game are the Infected: those infected with the BLACKLIGHT virus, and the Military. The Infected consist of ordinary civilians infected with the virus that are generally not a threat to Alex. However, the Hunters, huge creatures created from Infected water towers, are one of the main enemies in the game. Evolved Hunters referred to as Leaders are one of the most powerful creatures in the game and are incredibly hard for Alex to kill. The Military consist of ordinary soldiers which are usually not a threat to Alex, although they are capable of operating weaponry that is extremely dangerous to Alex, such as tanks and heavily armed helicopters. The Military also consists of BLACKWATCH, an agency dedicated to combating biological and nuclear warfare. BLACKWATCH is one of the intricate parts of the game's story and create some of the most deadly biological weaponry to combat Alex, including viral detectors capable of detecting Alex even in his disguise, and, introduced later in the game, the deadly poison Bloodtox, capable of slowly killing Alex and the Infected. Introduced later in the game are heavily armored and durable soldiers referred to as Super Soldiers, capable of fighting against Alex and some of the strongest Infected.
In order to gain more advanced upgrades, Alex is capable of sneaking into Military Bases using a disguise and stealthily consume various officials within the base. He can also set off an alert within the base, in which the only way to escape is to slaughter whoever is in the base. Alex can also gain upgrades from the Infected by collecting genetic data. Infected Hives, like Military Bases, are located all over the city, and produce genetic data constantly. Alex can destroy the Infected Hives or simply absorb the data on the outside as it is being produced. At the start of the game, only small factions of the Infected and Military are present in the city. However, as the game progresses, the Military and the Infected begin to expand. Territory in the city is made out of three distinct zones. Blue Zones are in Military control and are relatively clean of the Infection. Red Zones thrive with the Infection, although there still remains a strong Military presence. In some areas of the city, a Blue Zone and a Red Zone might converge, creating a new and distinct Purple Zone. In these Zones, the Military and the Infected are in a constant battle for control. How the player decides to act in these Zones determine which faction seizes the territory.
The game takes place in a medium-sized Manhattan with all his famous landmarks and place like the Empire State Building, the Chrysler Building, the Trump Building, the One Chase Manhattan Plaza, the Conde Nast Building, the Metlife Building, the One New York Plaza, the New York Life Building, among others.
The game follows Alexander J. Mercer (voiced by Barry Pepper) who wakes up in a morgue in the basement of Gentek, agenetic engineering company based in Manhattan, sending a pair of scientists that were just about to perform an autopsy running. Alex escapes, and witnesses the scientists being gunned down by military operatives. Alex is discovered and attacked. He survives bullets being fired into his chest, and leaps over a wall to safety. He soon discovers he now possesses powerful shapeshifting abilities, superhuman strength, speed, agility, durability, senses, endurance, weaponry and the ability to "consume" people to gain their memories, skills and appearance. With no memory of his previous life, Alex decides to find and consume those related to the conspiracy in order to uncover the truth. During his quest, Alex faces two factions: the United States Marine Corps and Blackwatch, a Fort Detrick special forces unit dedicated to combating biological warfare; and the Infected, monsters created by a virus known as BLACKLIGHT that is overrunning Manhattan. Captain Robert Cross (voiced by Jeffrey Pierce), a Blackwatch officer, is given orders to find and contain Alex.
Alex makes contact with his sister, Dana (voiced by Lake Bell), who assists him in tracking down targets, leading to the infiltration of Gentek headquarters. He finds a young woman called Elizabeth Greene contained in the building. Greene is a host for BLACKLIGHT and upon her escape unleashes it upon Manhattan. Dana directs Alex to Karen Parker, his ex-girlfriend. She agrees to aid him in stopping the virus, while requiring Alex to bring back samples of the virus. Karen later leads Alex into a trap, where he is confronted by Cross. During their battle, Alex almost defeated Cross when Cross mentioned 'Penn Station', triggering a flashback that leaves Alex dazed. Alex is injected with a parasite that threatens to kill him. Alex seeks help from Dr. Ragland, a pathologist linked to Gentek. Ragland helps Alex remove the parasite and turn it into a weapon against Greene. However, it has no effect on Greene as her body rejected the parasite immediately, and the rejected biomass forms a monstrous being, the Supreme Hunter, which Alex kills.
The origins of the virus and Elizabeth Greene are uncovered through a contact: in 1969 the government tested the virus' predecessor in Hope, Idaho, designed to target predetermined races. The virus mutated into something far more deadly, and the whole population was infected. Elizabeth Greene was the sole survivor; an anomaly in her body's biology accepted the virus, rewriting her genetic code along with that of her unborn son, codenamed PARIAH. The remaining population of Hope, Idaho, was liquidated by Blackwatch. Greene and PARIAH were kept in captivity for further research.
Alex discovers his own past: Blackwatch shut down the Gentek project due to leaks and ordered all project personnel eliminated. Alex Mercer took a sample of BLACKLIGHT as "insurance". Eventually pinned down by Blackwatch in Penn Station. Alex, in a final act of desperation and vengeance shatters the vial containing the BLACKLIGHT, releasing the virus before being gunned down. The virus entered Mercer's bloodstream through the bullet holes and repaired his body at the cellular level.
The contact and Alex pump a new "BLOODTOX" biological agent underground in order to drive the virus above ground where it can be fought directly, causing Greene to emerge, encased in a towering monstrosity. Greene falls from the monster in human form once she is defeated, and is consumed by Alex. Through her memories, it becomes apparent that General Randall, head of Blackwatch, is prepared to destroy Manhattan with a nuclear weapon. Alex, with the help of the contact, revealed to be Cross, infiltrates the USS Ronald Reagan to stop Randall. Once Alex consumes Randall, Cross is revealed to be the Supreme Hunter, who assumed Cross' identity after consuming him, and attacks Alex, asserting that when Blackwatch leaves NYZ they will no longer be searching for infected, and that after he consumes Alex, he will then be strong enough survive the nuclear detonation. Alex defeats the Supreme Hunter and moves the weapon out into the Atlantic Oceanwith a helicopter, where it detonates and catches him in the blast. His remains float back to the city and regenerate after consuming a crow.
During the credits, it is revealed that the public considers the military to have been the one who stopped the infection; a US Senator is heard telling the media that the events in Manhattan were a case of nuclear and biological terrorism, and promises retribution upon those responsible. Alex, reflecting on the events that occurred and the truth he uncovered about himself, claims he has "become something less than human, but also something more". After the credits, Manhattan is shown to be slowly recovering, the virus has been almost completely eradicated. Alex, standing on top of the Reuters Building in Times Square, comments that his work is almost done.
