If you preferred those "custom" Portal 2 turrets from Valve's promotional trailers, then Gaming Heads has a figurine preorder for you.
The Portal 2 "Turrets" trailer,where Cave Johnson offers custom versions of sentient, death-dealing robots to customers, was simply a humorous joke that advertised the game. Still, I'd be willing to bet money that somebody watching that video thought to themselves: "Yes! I can't wait for the statue versions so I can buy the whole set!" So far, most of Valve's plushies and miniatures follow the standard turret design, but videogame collectibles company Gaming Heads has finally produced a version that would prompt Cave to fire his creative team: The limited edition Aperture Science Sunburst turret, complete with motion-activated lights and slightly creepy sound effects.
I'm not sure to what extent Sunburst turrets are in demand among collectors, but they appear to be very high-quality. The model was crafted using Portal 2's actual in-game assets, rendering the custom turret as an impressive 16" figurine. A motion sensor has been fitted onto the turret's eye, activating its light and a few choice quotes whenever a target approaches. Of course, quality comes at a price. A single Sunburst model will set you back $325, which may seem high for a model purposely designed to look ridiculous.
Also, when I say this is a limited edition, I mean really limited; Gaming Heads will only produce 350 copies of this particular model, at which point Aperture Science fans will be out of luck. The company did a similar run for its standard while turret model, which as you can see from its store page quickly sold out. If getting a Portal 2 turret that can talk is really important to you, you'll probably want to get onto the pre-order page right away.
