Seeing a lot of reviews of the figures but is anyone playing the game yet?
I played the 3 first scenarios. The game is really great and we had a lot of fun. I have to admit that it is harder with 4 players as you get less survivors like zizi666 said, but when you choose your survivors according to the scenario (tough or speedy survivors) you manage to finish the game (unless the zombies get a double turn...).
You should read the rules on the offcial website. They also have a great support page with a campaign, new scenarios and a map editor to create your own scenarios.
At first glance the range combat system seemed weird as you play clockwise without the opportunity to play a specific survivor before another one (like in Last Night on Earth, Pandemy or Descent), but that's not a bad idea as it provides a real challenge and strategy.
I played a lot of zombies boardgames (Last night on Earth, Zombies, Off the Dead, Les Morts aux Trousses,...) and this one is my favourite. And it's a cooperative game so no one is bored playing only the zombies. I would recommend it.
