Zombie Crashing

Oh no, there is a zombie invasion; they are so meny that we don't really know what to do. Luckily, the zombies are coming on the street and you own a truck. A big heavy fast truck that can smash anything. So here is your mission. Smash as many zombies as possible and but be aware: not only zombies are running on the street, there are also innocent people you have to protect.
