Crysis

CRYSIS is an acronym for CRYogenic Stockholm Ion Source. CRYSIS is an ion source of EBIS type, and is located in Stockholm, Sweden.

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 of a trilogy. A separate game entitled Crysis Warhead was released on September 16, 2008, and follows similar events as Crysis but from a different narrative perspective. At the time Crysis was released, and years thereafter, it has been praised for its milestones in graphical design (commensurate with high hardware requirements).
