Prodagenâ€™s Flex-Fire system for the Playstation Move provides a gun-shaped bracket in which to mount the Move and Navigation controllers. Thus, the Flex-Fire is similar to Sonyâ€™s own Sharp Shooter battle rifle system, but Prodagen aims to ameliorate the Sony design in a number of ways. The most obvious difference is its aesthetics: The Flex-Fire is black and vicious, whereas the Sharp Shooter resembles yet another Nintendo Wii add-on, but one that is making a half-hearted effort to imitate a phaser rifle from Star Trek: The Next Generation (yes, from 1987). But the more important innovation of the Flex-Fire is its articulated barrel, which allows one to hold the rifle steady with one hand while turning its muzzle with another, increasing the speed with which one can adjust oneâ€™s aim. Read on to see what this means for your game.
