I bet if you were to make a game that featured a cast of characters that includes demons, zombies, koala-men, Yetis, King Kong, vampires, werewolves, and wizards you'd make a twin stick shooter. What's that? That's a terrible idea? Yeah, I guess it is a pretty awful idea. Good thing the developers behind Ugly Americans: Apocalypsegeddon thought the same thing… Oh right, they didn't.
