A: Yeah. Sorry about that – but that doesn’t mean all is lost! You still have many options open to you:

You could get rid of or steal their Repellent (Actions: Trash a Keeper, Steal a Keeper, Exchange Keepers)
You could make their Repellent Not Work (Rule: It’s Not Working!)
You could get yourself a Sonic Tranquilizer (Keeper)
You could kill your zombies extra dead (…And Stay Dead!) or get rid of all zombies (No Zombies)
…or hope that you all can just make friends with the Zombies because Zombies Ain’t So Bad (Rule)!
