The game which Gods create

Gods choose humans as their avatars to play the game of the gods. Humanity has sunk deeper into the abyss; more and more people enter hell after they die for their punishment. Even though Earth has great heroes such as batman and superman the evil keeps on rising. In order to stop this madness, the gods have decided to grant power to people who deem worthy, but the power of the god has a heavy exchange; to some are physical, and to some are emotional. Those people are called Champions, their mission is to catch Shadows, creatures that are born from negative feelings and can only bring chaos and distraction.
