Google announced yesterday on Google+ the launch of Collectibles Week. For a limited time, Android gamers will be able to enjoy special in-game content for certain games that are currently available for download in Google Play.

While you shouldn’t expect epic items, you may as well have some fun discovering some of the exclusive collectibles that can be found in around 20 Android games:
