I find this board very tricky with lots of strategy, I also find it one of the most balanced boards I have played, with the humans needing to really work as a team up against large number of Zombies, but the Zombies only have a limited amount of moves, which simulates the "shuffling" nature of Zombies and they cant move very fast, the only drawback is that after the 4th round the game is pretty much decided. Although, I have never seen the Zombies open the barn effectively, which may be an interesting gambit?
