As Cookie Monster says: "Zombies kinda 2007" (Yes really. Look up the teaser trailer for Once Upon a Monster). Disregarding what is basically just an artifact of personal taste, this is a fairly slick little system covering people in a stressful situation, which I believe is original, or at least I've not seen anything like it before.
I'm personally not a huge fan of using playing cards, and some of the layout and usage is less than clear, as is the core gameplay loop. I've just done a read-through, so it may be clearer in play. An example would probably help.
