I want to be excited for this, I really do. My sister and I had some great Co-Op games with this and although the game had some flaws, I really did enjoy it over all.
I'm not happy with the fact that it's the same cast of characters but an -alternate reality- nonsense story, don't know why they just couldn't do a sequel or another set of characters all together (unless it's laziness). I'm sure I'll play it through the campaign just to get in some good zombie slaying but won't play it after that.
