Attack on fatboy

The intergalactic warriors are in the middle of a fierce battle against aliens. The extra-terrestrials have invaded our planet and started to destroy everything. You must purge them from the planet. These guardians (thats what we call the earth warriors) are preparing to clean up our planet and protect it from harm; to do this, they need your help. But watch out: Their boss, the Fatboy, will not let you achieve your goal.
