Here is a simple scoring system you can use for your WZA! games that a fan came up with. Thank you Steven Rogers for this cool idea.
"Simply put, each player receives 10 points for each zombie that he/she kills by the end of the round (R.I.P.). In addition, anyone who lives through a round of play receives 50 points. The winner of each round of play (i.e. the player who scored the most points) gets to choose which version of the rules will be used for the following round. So an evening of play often switches back and forth between the standard rules and the Zombie Arena alternative rules. It makes no difference, the scoring is the same. The first player to 500 wins! Of course, you can set any value for the winner."
