Picked up a copy of this last night... and I haven't stopped playing.. omg its like a crazy zombified/military Assasins Creed... x10 in awsomeness.. Nothing like jumping up 600 meters and tearing a helicopter apart with a Sword made from your own genetically modified arm... or perhaps jumping on it from a skyscraper and HiJacking it??
I LOVE IT!
