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.
