Hi,
here are 3 pictures on what was in the box.
1st pic: the minis. They are much better than the average boardgame, but worse than most of the minis we paint here. But as I take Zombicide as a boardgame first it's completely ok imo.
2nd pic: cards with the heroes. What here interesting was, that the cards for Nick-Dave-Cholo were also in there despite them being wave 1 minis.
turn these cards and you get:
3rd pic: the zombi version cards. And here is the reason those 3 were again included, they have the same 2 sided card as the others, so it's because of the zombiversions.
edit:
I don't know why you needed the cards, they are viewable on the maker's site with stats and art(for example:
