For a long time, scientists believed that Mars was an uninhabited planet, even when ice was found there, which already indicated that there was some kind of life there and it was. It turns out that the Martians did not live on the surface, but inside the planet, and sooner or later earthlings would have known about it. But the Martians decided not to wait for exposure, they boldly attacked our planet. Thus began the epic called Metal vs Martian. The earthlings turned out to be ready for the invasion, they have already formed an army of robots so as not to endanger people. You will control it by placing bots of different strength and value in front of the waves of Martian attacks in Metal vs Martian.
