Remember The Gadget Show's FPS simulator that we showed you last week? Armed with naught but a pre-release level of Battlefield 3 and £500,000 ($650,000), it transformed a Birmingham studio into the sort of game room only multi-billionaires can dream of (as long as the dreams involved getting shot back, the sim comes packing paintball markers). The episode, which shows how this slice of gaming greatness came to be, has just finished airing here in the UK, where streaming and catch-up services aren't available to those outside the country. Fortunately for you lot, our friends at the show have uploaded the feature for you to watch in all its glory after the break.

Racing simulators are ten a penny, but the closest an FPS player will get to an immersive experience is buying some branded peripherals. Armed with a pre-release level of Battlefield 3, The Gadget Show enlisted a team of design experts to transform a Birmingham studio into an FPS simulator costing £500,000 ($650,000). A four by nine meter video dome surrounds the player as they stand on an omni-directional treadmill that lets you walk wherever you want to go. Ten infra-red motion tracking cameras and a sensor on your gun enables the picture to follow where you point it and a Kinect hack controls your jumping and crouching. The fun doesn't stop there -- 12 paintball markers mean that every time you get shot in the game, you'll feel it. The show airs in the UK on October 24th at 8:00pm, Channel 5. We've got a behind the scenes gallery below (supplied by those lovely people from the show) as well as PR and a trailer after the break.

Ever wondered how well playing Call of Duty at maximum volume mimics a real combat experience? Researchers at the Missouri University of Science and Technology must have asked a similar question, because they've built a 64-speaker surround-sound audio battlefield designed to train new troops. The system reproduces screaming fighter jets, rumbling tanks, and persistent gunfire -- all the better to acclimate recruits to the overwhelming, disorienting cacophony of warfare. Veterans say even with the four large 20-hertz subwoofers, it's nowhere near the real thing: combat volume is 25 percent louder than the average rock concert, at levels that can cause permanent hearing loss. Still, the creators say every bit of training helps; having near-combat experience is certainly better than none at all. So tell that to your neighbors next time they bang on your wall.
