Crysis is a first-person shooter video game developed by Crytek and published by Electronic Arts for Microsoft Windows and released in November 2007. It is the first game in the Crysis series.[2] A separate game entitled Crysis Warhead was released on September 16, 2008, and follows similar events as Crysis but from a different narrative perspective.[3][4] At the time Crysis was released, and years thereafter, it has been praised for its milestones in graphical design (commensurate with high hardware requirements).
The game is based in a future where a massive ancient alien-built structure has been discovered buried inside a mountain in the fictional Lingshan Islands, near the coast of the East Philippines.[5] The single-player campaign has the player assume the role of U.S. Army Delta Force soldier Jake Dunn, referred to in-game by his callsign, Nomad. Nomad is armed with various futuristic weapons and equipment, most notably a "Nanosuit" which was inspired by the real-life military concept of Future Force Warrior.[6] In Crysis, the player fights both North Korean and extraterrestrial enemies in various environments on and around the island.
