Crysis

Crysis is a first-person shooter video game series created by Crytek. The series revolves around a group of military protagonists with "nanosuits", technologically advanced suits of armor that give them enhanced physical strength, speed, defense, and cloaking abilities. The protagonists face off against hostile North Korean soldiers, heavily armed mercenaries, and a race of technologically advanced aliens known as the Ceph, who arrived on Earth millions of years ago and have recently been awakened. The series consists of three main installments, a standalone spinoff of the first game with a separate multiplayer title, and a compilation. A fourth game, under the working title of Crysis 4, was announced by Crytek on January 26, 2022.

Characters in Crysis use nanosuits, advanced powered exoskeletons developed by the U.S. military that grants them special abilities through dedicated "modes", as well as the ability to switch between them at will. Nanosuit's "armor mode" enhances the suit's ability to withstand bullet and shrapnel impacts, "strength mode" greatly enhances the wearer's physical strength, to the point of being able to punch cars through the air; and "speed mode" allows the wearer to run and act extremely fast. Lastly, "cloak mode" activates the suit's optical cloaking device that makes the wearer near-invisible.

The first two games, Crysis and Crysis Warhead, take place in 2020 on the fictional Lingshan Islands, off the Philippines. The protagonists of both games both belong to the fictitious "Raptor Team", a United States Army Delta Force unit that is sent to the island to investigate aggressive behavior by North Korea. The player uses various weapons, including traditional projectile weapons like handguns, submachine guns, assault rifles, and sniper rifles (all of which can be modified with scopes and attachments in real-time), as well as explosives and the nanosuit's natural abilities. Multiplayer gameplay modes introduce fictional futuristic weapons based on the ice technology introduced by the alien antagonists who are later found to reside on the island. In single-player, Raptor Team faces off against both the North Korean military and these alien foes.

Crysis 2, the sequel to the original game, takes place in 2023 in New York City. The protagonist is a new character, a U.S. Marine named Alcatraz. The nanosuit in the game (dubbed "Nanosuit 2") is a streamlined version of the original, without separate "strength" and "speed" modes, rather performing context-sensitive acts of enhanced strength or agility, but retaining the separate "armor" and "cloak" modes.

After Helena Rosenthal sends a distress signal saying the North Koreans are invading the seemingly unimportant island on which her team is working, the US government dispatches Raptor Team, a group of nanosuit-clad soldiers. After arriving on the island, however, Raptor Team's ranks are thinned by mysterious flying creatures, eventually leaving only Nomad, Psycho, and Prophet, who is subsequently kidnapped by the organisms later called the Ceph. Nomad rescues Helena but is eventually trapped in the alien ship after it unleashes an "ice sphere" on the island, freezing a great deal of the island. Nomad escapes the island with Helena and an oddly-behaving Prophet, and returns to the US carrier fleet, where he finds Psycho. Prophet returns to the island, which is subsequently nuked in the attempt to kill the aliens. However, they only grow stronger from the energy. The aliens launch a massive attack on the carrier fleet, successfully destroying it. Nomad, Psycho, and Helena escape and receive a distress signal from the still-alive Prophet, and decide to return to the island.

During Psycho's own mission, he was sent to retrieve a captured alien from Colonel Lee and the Koreans. After numerous setbacks and the assistance of his friend O'Neill, Psycho successfully defeats Lee, obtains the alien, and brings it back to the carrier fleet. At this point, the story continues in the original title.

A sequel set 3 years after the first game, Crysis 2 takes place in New York City in 2023, which is infected by an unknown virus. The player controls Alcatraz, a U.S. Marine who is found almost dead by Prophet, and given the upgraded Nanosuit 2 before Prophet commits suicide. He is tasked by Prophet to rescue a scientist named Nathan Gould. At first, Alcatraz has to face Crynet's CELL agents, a mercenary force who is hired by the U.S. Department of Defense to police the chaotic Manhattan, still thinking that Alcatraz is Prophet who is infected by the virus. After discovering Ceph capsules and Catalyst, the Ceph take over as the main antagonists for the rest of the game. Alcatraz and Gould team up with Tara Strickland, an undercover CIA lieutenant, and Jacob Hargreave, the original creator of the nanosuit. Alcatraz eventually enters the Ceph core spire and wipes out all the Ceph in New York. Now facing death again, he meets a memory pattern of Prophet, whose DNA is merged into Alcatraz's. The game closes with Alcatraz being contacted by Karl Rasch, a nanosuit scientist, and vowing to continue the war against the Ceph.

As with its predecessor, Crysis 3 again takes place in New York. Set in 2047, the game sees Prophet return to the now nanodome-encased New York City, on a mission of revenge against CELL, having uncovered the truth behind their motives for building the quarantined nanodomes.
