Some of the meanest characters from cartoons have escaped and are wreaking havoc for everyone! It's up to the heroes... or what passes for heroes, really, in the case of a lot of these shows... of the various comics to put them back where they belong. That's the story behind Cartoon Network Crossover Crisis, available now from Cryptozoic.
The game draws (uh... no pun intended) characters from such cartoons as Adventure Time, The Amazing World of Gumball, Clarence, Courage the Cowardly Dog, Dexter's Laboratory, Johnny Bravo, The Regular show, Samurai Jack, and Steven Universe. It uses the Cerberus Game Engine that you might know about from the DC Deck Building Game, also by Cryptozoic.
You can pick up Cartoon Network Crossover Crisis in your LGS now.
