@taamvan Well, that’s another strategic angle. The defender needs to weigh that possibility, and consider the ramifications of leaving a zombie in a territory and an attacker’s ability to capitalize on the situation.
Note how AAZ OOB is similar to 1941, but, it has artillery. This provides another strategic consideration to balance- do you buy more arty to sacrifice in order to keep the zombie hord numbers lower or not? Then the Z4 rounds come into play with a 2:3 chance of hitting a zombie on attack when faced with all zombies.

I think the broken issue is that the tournament removed the cards. If you had chainsaw tanks, z-4 rounds, and DOTS, you’d have more tools to work on the Zombie problem- along with being able to move zombies and stuff.
I’m new to AA, but from everything I’ve been reading, I love that zombies create a neutral variable that can be strategically applies like a fog of war. Some game re-caps seem like attempts at WWII Operation reenactments where if the dice rolls don’t pan out, one side surrenders, maybe re-set the board.
