Escape of The Dead

You are a survivor of a zombie apocalypse and you're stuck in a house with a broken car and hordes of zombies are attacking in the lawn. But wait, you found tools enough to fix the car to escape from the hordes of zombies. ARE YOU READY FOR IT? Escape of the Dead is a solo game. In the game you are trying to fix the car while trying to defend yourself against hordes of zombies. You're given 4 Action dice per turn, distribute between 3 sections of the game (either by shooting zombie, fixing the barricade and/or fixing the car). Roll for success on each section. Any zombie that survived will attack the barricade. When you have successfully killed 10 zombies you will be rewarded with power-up. You lose when your barricade is down (i.e barricade's hp equals zero). You win when the car is fixed 100% and get out of the house.
