Haven't played it much.
however it has the best feature ever
you can scream "grenade" at the Kinect when you want one

I'm about half way through, loving it

i cant do much as i have a dodgy shoulder.
you playing with kinect?

Am I imagining it or does it seem light on save points?
seems Im haviung do to do loads before reaching save points
Also I get a sporadic lightning sound when i use a frag grenade
