At the Game Developers Choice Awards show last night, Double Fine revealed its third downloadable title (following Costume Quest and Stacking), Trenched, which looks like it mixes third-person multiplayer mecha action -- the twist for these customizable mechas being a hybridization of "mobile firepower and stationary defenses."

As this is being published by Microsoft, this is releasing for just Xbox Live Arcade -- sorry, PS3 owners! Double Fine, which is also currently working on an Xbox 360 Kinect game based on Sesame Street, hasn't announced a release date or expected pricing for Trenched yet.
