Metal Slug: World at War

Two individuals lost everything they held dear thanks to a corrupted group of "heroes". One day, they enlisted to a group known as the Peregrine Falcon Squad, led by the charismatic Marco Rossi who helped them to train for the battle against General Morden and his army. What they didn't know, is that they would become a duo of Giants of Light ready to combat various kaiju and alien threats, including for Mars People. But now, they have a triple trouble: Morden's return, Mars People's new invasion and the very group of false heroes who plan to stand in their way to save the world. This is how two alternate versions of Daikaiju and Megaforce Heroes start their mission.
