Allow Zombies to infect adjacent terits, limiting the number of hits in adjacent regions...thereby allowing Zombies to take total control of the game (win).
Developing map boards that have Nuke/Zombie free zones.
Using cards to develop weapon/research to limit the use (effect) of nukes, Zombies, etc.
How this would benefit the game; Diminishing the dice while adding strategy to the game.
Dice games vs card driven war games...the cards have it.
