Lamda Mercedes: Secret Garage

The "Secret Garage" activation was created to raise awareness on the Lamda Mercedes dealership and promote its facebook page.
So, what's the secret? One garage, a lot of Mercedes cars and 3 security cameras. Users have to observe through the cameras and try to count or guess the number of hidden Mercs inside. If they give the correct answer, they are entered in a draw. But it's not that easy. Another challenge lies within. Only one camera is "on"so it's hard to make a lucky guess. For a user to be able to look through all 3 cameras, he has to "unlock"them using shares and invites, to release the app's full potential
