Rather good, as far as these WWII shooter games go. I find CALL OF DUTY a much more interactive and NPC reliant game. Having to depend on your fellow 'soldiers' for cover and support, adds to the general realism of the gaming experience. It's also alot easier than games like MEDAL OF HONOR and induces far less frustration and therefore is much more enjoyable. Some in-game situations may prompt a little nervousness and intense adrenaline...but that just makes it all the more entertaining, right?
What's not to love? ;)
