Defense Grid: Resurgence Map Pack 3 is now available though Steam, for $0.99 USD, adding new maps, and achievements to Defense Grid: The Awakening, Hidden Path Entertainment's strategy game. Here's word from the update on Steam News: "Today's Map Pack 3 release includes two more challenging environments - Urban Planning and Tactical Diversion. It’s the third of four great map packs in the Resurgence series. Urban Planning is a dense environment with restrictive build spaces, forcing difficult decisions against continuously attacking hordes. In Tactical Diversion, survey the small, snow covered platform and consider numerous possibilities. But be prepared for the aerial assault!"
