The new upstart that appeared out of no where to have a wide following in central Pennsylvania. Is raising alarms at the Foursquare corporate location. The breakthrough with lockbreaker is that technically speaking Starbucks could launch a full scale advertising campaign in Dunkin Donuts.
The GPS driven app, though in extreme levels of Alpha, has the potential to cause disruption to the traditional foursquare mayor and sponsor model.
Lockbreaker allows for difficulty within gameplay for sponsors to allocate prizes while on location. Hence allowing for larger sponsorships. The game launched in stealth a few weeks ago, and worth of mouth spread it. A new version of the android app was published this morning. The game also has a webapp for iphone and other models.
With zero marketing and with a stealth launch there should be zero players, however Lockbreaker has exceeded Foursquares market penetration in some markets.
