Crysis is a first-person shooter video game series created by German developer 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.
Characters in Crysis use nanosuits, advanced powered exoskeletons developed by the U.S. military that grant 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.
