I made this for another thread:
Skill (1d6-2 or 1d4)
Bite: Close combat, 2 Use, 1d6 damage
Zombies can not use any weapons aside from its bite.
If a Zombie is hit by an attack, flip a coin. On a tails, the Zombie takes no damage.
If a Zombie deals enough damage with his attack to kill a living creature, flip a coin. On a tails, the creature comes back to life the next turn in the control of the player who owns the Zombie. The new Zombie creature has -1" move and its skill goes down by one level.
