This is the NUMBER ONE expansion for Zombies the Board Game. The others are fine, but this one doesn't add time to the game, just a little extra fun to the primary set by adding more event cards. The art is awesome or gruesome, it's your choice, (All time favorite event card concept however comes from the Humans expansion. Look up Breakfast, Lunch and Dinner, you'll laugh or cry, if the latter, then this really isn't your board game). Seriously, if you have Zombies the Board Game, you CANNOT go wrong by adding this one.
