Before a game of Munchkin Zombies, I had the idea to add a little something to the game. I grabbed Zombie Dice and made up a little rule for combat bonus...
So during combat on YOUR turn, you have to option to grab the cup and roll for a bonus. If you don't know the rules, you can look at them here
http://www.sjgames.com/dice/zombiedi...es_English.pdf . Follow rules normally. You can get a +1 bonus to your combat for every brain you roll but if you get 3 shots, you get a -1 for the shots and a -1 for every brain you acquired before the shots(say you got shot 3 times and had 3 brains on the table it would equal a -4 to the rolling munchkin). Bonuses last for the current combat only and usable only once per combat.
It worked out quite well and we had a lot of fun with it. A tweak we may try next time is a -3 for the shots and -1 for the additional brains. Or maybe a lingering negative to combat if you are killed by the dice.
Just thought I would get my idea out there. Thanks :)
