Crysis is a science fiction first-person shooter video game developed by Crytek Frankfurt, Germany, published by Electronic Arts for Microsoft Windows, and released in November 2007. It is the first game of a trilogy. A separate game entitled Crysis Warhead was released on September 12, 2008, and follows similar events as Crysis but from a different narrative perspective. Crysis, Crysis Warhead and a multiplayer expansion called Crysis Wars were re-released as a compilation pack titled Crysis Maximum Edition on 5 May 2009. At the time Crysis was released, and years thereafter, it has been praised for its milestones in graphical design (which commensurated with high hardware requirements.)
Crysis also supports mods and custom maps, and is included with a sandbox editor.
