If an enthusiast-built Portal 2 turret piques your interest, Gaming Heads' Valve-licensed miniature replica may very well force your wallet open. Modeled using Portal 2's in-game assets and cast in "high quality poly-stone," these mini-turrets aim to intimidate intruders with a motion activated light-up eye. In addition to the stoic and silent basic model, the company's offering an exclusive edition, which plays sounds and voice samples from the game. Only 1,100 of these hand-painted facsimiles will be produced (350 with sound, 750 without), but the company notes that other figures based on the adorable death machines are in the works. Pre-orders have already begun, so collectors will want to act fast -- provided they're ready to pony up $300-325, of course.
