New Map

With this patch a new map arrives in the form of Ruins. This map is set in a church ruins environment and invites players to fight both inside and outside of the church itself. Below you can find a flythrouh video.

Crysis Wars features three multiplayer modes, including TeamInstantAction, a new match type that mixes fast-paced action in a team-based environment, in addition to the insanely frenetic gameplay style of InstantAction and the hardcore team-based PowerStruggle, both of which return from Crysis. The game will include 21 maps, six new maps for TeamInstantAction and InstantAction, and one for PowerStruggle and Crytek will also have a support team dedicated to meeting the needs of the Crysis Wars community.

Ruins is set in a church ruins environment where players are able to do combat both inside and outside the ruins.
