Battle Snake

From Alive Games:

Once upon a time, in a distant galaxy, there was a 'snake' planet. Nothing ever disturbed their peaceful life on a wonderful planet until it was invaded by evil robots from another galaxy.

You can save the snakes from destruction and slavery by cleansing 80 specific ares on the planet from aggressive machines. You must also battle with a robotic leader which constantly enlarges the population of it's subordinates. Remember snakes need your help!
