Codename: Dead Bird (CDB) is a singleplayer total conversion for Crysis. CDB puts the player into the Iraq War and focuses on intense modern infantry combat in urban and desert environments. After Iraqi Terrorists assassinated the US President, his successor and western allies started a new Iraq offensive. But instead of giving up, the insurgent forces grew. They even gained control of a Russian fission bomb. To eliminate this new threat the CIA started Codename Dead Bird. A special task force commanded by the player now has to fight the terrorists and diffuse the bomb.
