The adventure takes place in the CN world, where an alien invasion has taken place. The world has 60 play areas where players team up with one another and CN characters to defend the universe against this alien invasion.

Characters from Ben 10, Foster’s Home for Imaginary Friends, Ed, Edd n Eddy, Dexter’s Laboratory, The Powerpuff Girls and other CN properties will populate the online world.

"We are excited to bring the first AAA, browser-based MMOG for kids to the marketplace and expand the category of interactive casual gaming," said Turner Broadcasting System’s animation young adults and kids media group SVP (digital) Paul Condolora. "Unity Technologies shares our vision of providing easily accessible, dynamic gaming experiences and we are pleased to deliver on this promise."

For the cross-platform browser support, CN is using Unity3D, a game development engine from Unity Technologies that originated on the Mac. In addition to cross-platform native application deployment, Unity supports a browser-based architecture that works using a plug-in.
