Kinda Funny's reaction to the behind-closed-doors demo. Makes the game make a lot more sense.
As to the "they're not zombies, they're freakers" thing, it's actually a fairly significant distinction in that they're in fact "alive" (seemingly more so than TLOU pseudo-zombies) in that they need to eat and sleep. A specific thing they mentioned was that they hibernate during the day, which makes it possible for you to scout out the location/lay traps before actually tackling that zombie horde. This explains how you would know where to go and what to do in terms of triggering all of those traps and using all of those shortcuts.
The fact that they're alive also effectively justifies them seemingly dropping from a single shot of a submachine rifle, as I think any one of would as well, seeing as how they're actually alive.
Criticizing the game is cool and all, and more productive for them than lavishly pouring on half-truth praise, but I really wish some people here would at least cut these guys some slack.
