MojoKid writes: The cool thing about playing Duck Hunt on the NES back in the day, was that you got to point a plastic gun at the television and shoot directly at fowl or clay discs. It offered a deeper level of immersion than what would have been possible with a standard controller. Such is the pitch for a new Kickstarter project called Rail Gun. Rail Gun is a series of attachments designed to work with your existing Air Soft gun. The pieces attach to any standard Air Soft gun to give you a "truly realistic and immersive experience for FPS games." There are five units that comprise the Rail Gun. The Main Unit houses the power and sensitivity buttons; the Jog Unit has an analog stick, special action button, and a few other components; the Weapon Unit lets you cycle through weapons, walk, drop items, and so forth; the Trigger Unit features the trigger and buttons for jumping, zooming, reloading, and crouching; and the USB Unit is what plugs into your PC or console. The Rail Gun uses fast rotation technology to track your vision based on where you're pointing your Air Soft gun. It also uses an algorithm to enhance aiming by detecting minor hand trembles, and you can adjust the sensitivity of this to your liking.
