The subways clearing gave new hope to the people of earth. While you were busy clearing out the New York invasion, the cyborgs have been positioning their space stations around Earth to begin using them as invasion strongholds. It’s time to take the fight to them and send whats left back to where they came from. As the hero "Pain Train" you feed off the pain you inflict. This enables you to take on hordes of enemies that would otherwise overrun a normal man. Shoot your way through 12 new gore packed levels, craft new weapons, earn 30 different weapon skins, beat multiple difficulty modes, and destroy all of the overlords. Pain Train is entering a space station near you, "All Aboard!"
