As a huge Left 4 Dead fan, I was so excited when I heard about this game. I played the beta repeatedly with my group of friends and we had a blast. We haven't even made it halfway through the campaign and it's all I want to do. I am loving how much harder it can be. The new special zombies are crazy and exciting. It feels like L4D evolution. Does it have some launch issues? Yes. But with the minimum problems to be fixed, the sky is the limit for Back 4 Blood.
