Thought I'd start a topic on this, which was out on Friday.
I loved the last one which was set in WWII Berlin, and has moved to the North African desert for this in what is again a WWII outing. It really is nothing more than a sniping game, but it's beautifully realised, with slo-mo bullet cameras, and magnificently gory X ray shots of your bullet shattering some German captain's skull or turning his internal organs into mincemeat. This one's quite a bit less linear than the last one as well, which is nice.
There's also the option to play it on a 3D telly, and that in my mind makes a great game, just absolutely brilliant.
