Crysis is the first game in the Crysis series and was developed by Cyrtek before being published by EA in 2007 for Windows PC; it was later released for the Xbox 360 and PlayStation 3.
The game is set in the future after an ancient alien-structure has been discovered; the player takes control of a US Army Delta Force soldier named Jake Dunn who is nicknamed Nomad. He and his team are dropped in with specially designed military "Nanosuits" to investigate the discovery and evacuate the native population of the island.
Their mission doesn't go as planned leaving Nomad as the last man standing and he must complete the mission by himself where he must deal with the increasing alien threat.
It follows the traditional gameplay seen in first-person games where the player has access to a wide range of weapons which are collected and exchanged throughout the game; this includes assault rifles, pistols, shotguns and sniper rifles. There are also a large number of usable vehicles in the game including cars and tanks which are used at specific points in the game.
Each level in the game can be completed using an aggressive or stealth approach; there are both bullets and non-lethal tranquilizers and most of the game can be completed without killing enemies. Enemies react to how the player acts throughout the game, they will react to noises made by the player and may call for reinforcements or become more defensive.
The Nanosuit features various modes to support the player's specific playstyle or their current actions. One of the most used modes is a stealth / camouflage mode which renders the player completely invisible to enemies; using the abilities of the suit requires energy which is slowly recharged. It can also highlight specific enemies for the player to track their movements.
Multiplayer in Crysis supports up to 32 plays in a single instance; there are two gamemodes to select from including a classic deathmatch style mode. Power Struggle in a team-based mode where two teams attempt to destroy the others base.
