Crysis

Crysis is another great action game from the creators of the popular Far Cry. The game takes place on an exotic island in the South Pacific (but you'll also see areas of frost and ice), where suddenly the sun is eclipsed as invaders freeze the place. The unidentified flying objects were first noticed by China and North Korea, whose governments have therefore sent their military there, but they are not having much luck... The Americans can't stand the sight of it anymore, and dispatch their Special Purpose Unit, which includes Jack Dunn, who you will impersonate.
