Hold the Line!

I've used Zombies +1 in a few scenarios, which were applicable to Standard and Feral Zombies - using the TP/BitF game. So wasn't applicable to behemoths. Pretty much balanced it off as a two dot points rating in the games we used it in. Thing to bear in mind by including Ferals, is they can now move 3 spaces.

Seemed to work out ok and was a lot of fun. Importantly, changed the Players strategic approach, so you actually do a get a different game and playstyle from it.

Never used Zombie Hand (6) as a permanent feature, so can't vouch for that. When playing TP/BitF though, the fewer cards more or less seems to dish out the Event Card that increased the Zombie Hand to 6 anyway.

In the few scenarios incorporating Zombie Hand (6) as special rules, I'd look to balance it off with what is equivalent for the Players from said scenario cards. Sorry, I don't have the game in front of me, to quote the Player's side of things. I'll come back later on it, if someone's not repied in the mean time.
