Crysis leads up to Crysis 2 and Crysis 3! According to Crytek boss Cevat Yerli the PC FPS game was always meant to be part of a Crysis Trilogy.
In an IRC chat Mr. Yerli said: “The game is designed as a trilogy, so you have two more installments to come and the ending [of Crysis] is planned deliberately. But I cannot answer any more questions here please as we want to keep some surprises for you all.”
He also mentioned Crysis’ first patch will be out by the end of November. To quote: “We are collecting up all the user feedback now and planning patches that will address as much as possible as fast as possible. The first patch will be out in 7-14 days”. — From Incrysis, via CVG
