Classic Call Of Duty game... The campaign is about 5-8 hours long (depending on difficulty and trophy hunting) You play both as an American marine C. Miller and as the Russian private Dimitri Petrenko. It's one of my favourite childhood games as a kid. Growing up me and my brother played it on our xbox 360 and I completly fell inlove with it. Call Of Duty World at war started my journey into the gaming world if I'm being honest. It's great especially if you are interested in Shooter games world war 2 and what not. Sure it has bugs here and there, but in all honesty they aren't that game breaking, none that I know of anyways.
I recommend buying it.
