Orcs Must Die!, a tower defense game from Robot Entertainment, invades PC and Xbox Live Arcade later this summer.
Published by Microsoft Game Studios, it tasks you with protecting your fortress from an army of monsters by any means possible.
While the prospect of yet another tower defense title might not set pulses racing, it at least has pedigree. Robot rose from the ashes of Halo Wars and Age of Empires developer Ensemble.
Though originally announced for "PC and consoles", Microsoft's involvement seemingly scotches any hope of a PSN release.
