I'm not much into third-person action games that often seem more at home on consoles than on PCs, but I've got to admit that this game looks like a blast:
Initially, the mention that NYC gets infected with zombies caught my attention. Then I learned that the game has a sort of open sandbox mode of play - that really caught my attention because I love free roaming games. Finally, this preview makes it sound like a must-have:
I hope they release a demo at some point because I am still leary about purchasing a $50 game like this as its gameplay is so radically different from what I usually like to play (slow strategy games). Still...the game has me intrigued.
BTW: Here's a gameplay vid which makes the game look like a lot of fun.
