The year 2030 was the year that man last step on Earth. Everyone thinks that they would rule the world forever, but that was the end of it. Soon, the animals evolve and began claiming the land. Now, they are fighting against each other to claim the land. The idea here is to defeat the rival tribe. You need to pick something and throw it at them. Once you eliminate most of the enemies in an area then you would win that area. That is how you expand your territory. There are many cities and you do want to conquer all the cities.
