Similar to the earlier games in the Crysis series, Crysis 3 is a first-person shooter. Players take control of Prophet as he progresses through New York City to defeat the Ceph, a technologically advanced alien race. Throughout the game, players can slide, sprint, jump and crouch. When encountering enemies, players can defeat them by using guns or a compound bow, utilizing explosives like grenades and C4, or by performing a melee attack.[1] Performing certain movements takes up energy from the Nanosuit, the armor worn by Prophet. Some abilities are not available for players to perform or utilize if the Nanosuit's energy is too low; they must wait until energy is refilled. As a result, players are tasked to manage the use of the energy.[2] The game's artificial intelligence was updated allowing enemies to react more quickly to players' attacks. Enemies can take cover when attacked, and can employ strategy to assist and support each other against attacks.[3]
