The Grim Adventures of Billy & Mandy video game pits the characters from the popular Cartoon Network television show against each other in an adventure-fighting game, filled with mayhem and chaos. In battle mode, up to four players can use a multitude of weapons in destructible arenas like the Desert of Doom and the Underworld to battle it out to be the last one standing. Players also have the option to play on their own or with a friend in adventure mode, a series of 40 story-based missions where players can unlock new weapons and additional playable characters like Irwin and Hoss Delgado.

To unlock the NPC's as characters: (I only know three now so bear with me.)
Nergiling and Mutant Chicken: Beat all the missions and beat story mode with every usual character in the game. You will unlock the Nerguling and the Mutant Chicken.
Viking: After completeing story mode with every regular unlockable character, go to the credits in extras. Destroy every letter in the credits by punching it, flamethrowering them (hint: Flamethrow Billy; he will destroy every letter he touches), and use Thor's hammer to destroy groups of letters that go above you with the "y" button attack. Good luck with it.
