I'm not sure if The Avenger—this elaborate Xbox controller exoskeleton—will improve your performance markedly. But my goodness, it'll make you look prepared. Or, you know, like your controller has polio.
The accessory claims to "enhance the gamer's manual dexterity and situational awareness" with its "stabilizer tripod, high-precision tension straps, hair-triggers, and sensitivity adjusters." All of which seems like a fancy way to say it makes the buttons bigger.
If you think your controller is one dominatrix suit away from total multiplayer domination, it may well be worth the $US60—especially with the 30-day money back guarantee. Of course, by then your controller and the Avenger will have mind-melded sufficiently to make them inseparable. That's how this works, right? [The Avenger via Kotaku]
