If I remember rightly they have one in Germany, UK and Budapest.
I think Germany and Budapest developed Crysis 1.
Cryteks UK studio were responsible for Crysis 2 (well atleast the multiplayer part)
Correct me if I'm wrong over a year since I read about it.
So where is crytek developing C3? Not that I'm going to infiltrate their studio or anything for inside information.
It could just determine the games fate.
