Your job is to destroy and eat everything you will find. Its not a simple game, because they will stop you, of course, and you can not afford it.
Show everything in you and where you can get.
Eat a few people, destroy things in the way and get really high enough scores to continue.
Unless you take all the people, you will not get any further, and the game asks you to come back.
Fight, jump, bite and destroy all the cars and humans in sight!
Have fun!
