German part of EA posted the minimum requirements for PC version of the Crysis 2 on the Facebook page and it looks like the upcoming Crytek Crysis 2 game isn't going to be heavy on hardware. Of course, bear in mind that these specs are going to run the game, but doesn't mean that you'll get all the eyecandy seen on trailers.
The upcoming Crysis 2 will apparently work on XP, Vista and Windows 7 OS and minimum specs include a Intel Core 2 Duo 2GHz, AMD's Athlon 64 x2 2GHz or better, 2GB of memory, Nvidia 8800GT 512MB, ATI HD 3850 512MB or better and 9GB of HDD space. It is also noted that you'll need an active internet connection, presumably for activation.
It is pretty obvious that the PC version of the game will not be a simple port. The game should launch on March 22nd in the US of A and on March 25th in Europe.
