Crysis

Crysis is a first-person shooter video game series created by 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.
