Robot Entertainment developed Age of Empires Online until Gas Powered Games assumed their role in February 2011. At the same time, they handed over maintenance duties of the ESO servers to Microsoft so that they could focus on their new game, Orcs Must Die!. In 2012, the company worked on Hero Academy for the iOS platform and the sequel to Orcs Must Die.
