FYI, in keeping with the Original -

stats range from 1-5 for players
Zombies have stats ranging from 3-4

Dice are rolled to see if something is successful.

Example - Defending yourself from a Zombie.

Player rolls a 3 six sided dice, and get 12
Zombie rolls 4 six sided dice and gets 13
Player is eaten
