Kill em Zombies
In Transylvania, everybody knew that vampire rules the land and nothing can oppose them. Sure, there are walking skeletons, but those can't rival to that of the vampires. But, one day, there is a new addition to the group of undead - zombies. The zombies came out of nowhere. No one knew where they came from, but only one thing is certain, this makes living a little harder for the humans. The humans can't take it no more, so they invented a monster truck that can take our vampires, zombies, and all things that goes bump in the night. This is the only way for the humans to survive in a place where the living are being raised like cattle.
Drive your truck as fast as you can till you reach the finish line. Drive over zombies, ghost and all the things that bump in the night for some added points. Barrels, tombs and other things that can be drive over also make a good way to make more points. Reach checkpoint after checkpoint and you can be assured that you won't start at the beginning if you crash your truck. The game gets harder and harder as you make some progress.
