Location-based Chinese Angry Birds game only works in McDonald's

This is clearly the future of mobile gaming - create levels that can only be played in certain places.



From AdAge:

"TBWA/Shanghai and TBWA/Gameplay (which is based in Helsinki and has a relationship with Rovio) developed the campaign, which gives special hidden game modes and free Power-Ups to McDonald's customers who are playing Angry Birds on their iOS devices. [...]
In addition to the spot and customized game, which features in-game advertising and is available on both mobile and desktop devices, the campaign also includes in-store promotions, online advertising, social and outdoor media. Consumers will also be given the opportunity to vote on a city that will get to build an actual "slingshot," outside its branch of McDonald's."

Groundbreaking!
