Well I played it for a couple of hours tonight and I gotta say, I'm pleased I didn't buy it. It's fun whenever you get to fight Zombies or B.O.W's, but the enemy soldiers you have to fight take so goddamn much damage it sucks whatever enjoyment I was having right out of the game. Forget having teammates because the AI spends most of it's time wandering in front of your weapon. All in all, it's worth a rental and a playthrough for nostalgia's sake to revisit old locales, but it is definitely not worth a $60 purchase.
