In addition to the single-player campaign, Crytek has also emphasized the multiplayer modes, titled Crysis Wars. In addition to the Instant Action and Power Struggle modes of the original Crysis, Crysis Warhead also features Team Instant Action mode, as well as 21 playable maps upon release. Crytek has made numerous changes to the multiplayer gameplay including tighter vehicle controls, weapon rebalancing, and Nanosuit alterations. Crysis Wars is included on its own disc, has a separate installer and logo, and is considered a separate game by Crytek; regardless, it comes bundled with Warhead at no additional charge.
