I quite like zombies because they are different from so-called "living opponents". They react differently, express themselves differently. While I clearly understand that it may be confusing and enraging for many people, it refreshes gameplay and makes in more variable: I need to develop other tactics, listen to reactions of them because I should understand where and when they are noticing me. It is different experience overall. So I have no problems with rating of "Where the Unknown Lurks"))...
Is it only me who sees that you created several same, identical topics with this review?
