Earthlings brought their planet to such a state that it becomes unbearable to live on it, and then the question arose of finding suitable planets in space in order to move there and start life anew. All resources were thrown at it and one was found. But it is much smaller in size than the Earth, so you need to look for more, but for now this one was left on the robot, which should protect against unforeseen guests, and those soon appeared. You have to control the robot in Orbital Survivor so that it destroys all incoming alien objects, preventing them from penetrating the atmosphere and landing. Shoot them in the Orbital Survivor.
