Looks like you're coming out of retirement, son. Another citadel was taken over by the forces of Hell, just when you thought you exterminated them all! This time, it's not so easy. The minions are more dedicated than ever, to take over the world! They've teamed up in larger numbers, and in tougher groups. This will be the toughest battle you may ever have been in, provided you can last through this marathon of gunfire.
