"Once you've taken out your foes, you can hop into a nearby humvee, which will seat your whole posse, and race off down the road to your next objective. While you make your way through the rough terrain, you'll encounter some resistance which you can deal with by manning the turret at the top of the car. An unexpected obstacle we encountered was a sandstorm, which obscured visibility, requiring us to switch to our thermal vision and take out some opportunistic baddies trying to use the storm as cover."
Sounds like they overhauled the single player campaign. Too bad there's still gonna be stealth missions...at least the new checkpoint system will make it less frustrating.
I wished they would comment on the framerate, but I guess it's too premature to say anything this early
