Well, that is not entirely true. I did manage to get the final near impossible achievement, "Nothing Special", which is getting through a whole campaign without anybody in your group taking a single point of damage from a special infected. I still have one more achievement, zombie genocidist (a nod to dead rising) by killing 53,595 zombies, which I have 24,000 abouts right now. It is inevitable I will get the achievement and 1000\1000 this fine, very fun game. If anybody needs some tips on getting those hard achievements, just let me know!
