Basically FarCry with a new coat of paint, which isn't necessarily a bad thing. The suit is a gimmick. There are only a handful of instances where its use is mandatory.
Demo was playable for me at 1024x768 on Medium settings using:
C2D 6420 running @ 2.7GHz
BFG GeForce 7800GT OC
2gb DDR2 @ 425MHz
anything higher than 1024x768 and it was too choppy/laggy.
In response to a previous post, the voice acting and plot are just as cheezy as FarCry. The "ethnic-macho-aggressive" voice acting is painfully detrimental to the immersion level. Apparently we lost a lot of personnel in Iraq; the recruitment standards for special forces have apparently seriously declined by 2020.
