Destroy All Humans.

You are an alien called Krypto and you have come to Earth to kill people and gather their brains for examination. There are three missions you must complete. Kill all the radioative cows. The cows were abducted by you because you thought they were the main inhabitants. When you found that this was not true you accidentally dumped the cows in a pool that was radioative from the nuclear plant next to it. The cows then became radioative and are eating peoples brains. You have to collect all the brains you can so you can not allow this. The second mission. Is to kill twenty humans and collect twenty brains. The third mission. Is to jump in the nuclear plant and become a giant from the radiation. Then kill everyone. And DESTROY ALL HUMANS!!!!!! Have Fun! Please post any arguments or comments. Thank you.
