Arena Of Wailing

People have been destroying the Earth for many years. Our planet fell into decay and people descended into underground tunnels. But not all could survive underground and many gradually rose resurfaced. It's your turn to check out what's going on up at the top. Upon rising up you saw the destroyed city and a crowd of mutated people. Only these are not X people, but evil mutants. What happened? It was all quite simple. People left the robots behind to clean the atmosphere, and now these robots turn people into mutants. But the air was actually cleaned. Now it's time to clear the city of the mutant people and let people rise to the surface and see the sun and the stars again. But this will be no easy task. Look for hidden weapons in the city, destroy the robots and defeat the mutants.
