I like some things about the game but after a while you realize it's exactly the same scenarios over and over and over again – scavenge for stuff to make weapons and food, kill zombies, kill people, repeat.
As far as I can tell, after you've spent a few "days" in the game, you've seen and done everything. Sure, there are minor differences in the neighborhoods, and the total number of zombies increases over time, but that's it.
And the character moves like he's made of rubber. When you pull out a rifle, it just bobs up and down. Or if you try to stab a zombie or open a cupboard, you'll often end up just flopping your hand into it.
Long story short, if it was $12 it would be worth it. But it is nowhere near what you'd expect from a $40 game.
