Rules lite but lacking the meat to be able to run more than a one-shot. Not the system to use for a full campaign of weird or dark fantasy.
Game is a great mix of the zombicide series and the night of the living dead series. Black plague is probably our favorite. Romero mode has its own versions of survivors.
This game is fairly similar to previous iterations overall. The initial playthrough is a small learning curve. The rulebook has quite a bit of information to absorb, but it is explained in great detail with lots of illustrated examples.
