At EA's live press conference, Crytek's Cervat Yerli promised 2 will have the most advanced enemy AI ever.

In the introduction to the play footage Yerli said: "Crysis 2 will feature the smartest enemies ever in a video game."

The gameplay footage showed some extremely intense combat in New York's Central Station culminating in a whole building falling down on the station.

Crysis 2 will be available on PC, and this autumn.
