Zombies!!! Third Edition adds rules for playing Zombies as a team in which both players must make it to the Helipad in order to win. Also, there are rules for co-operative play in which all players must make it to the Helipad without running out of life tokens. Finally, there are several scenarios in the game to vary game play.
In addition, Zombies!!! Third Edition contains four new zombies figures, survivor tokens for scenario play, and door tokens. The rules and the cards have also been updated. This set is fully compatible with all other Zombies!!! editions.
