Ancient machines evolved and captured the people of the planet. Get rid of old machines. Destroy them using a catapult and improved bomb. You can gain extra points if you get the artifacts. Good luck!
Nobody saw them coming. In the year 2465, aliens destroyed the planet Earth, and only 3,000,000 survivors are launched into space under your command. Help protect humanity against the alien invaders as you find a new Earth somewhere in the galaxy!
