*Warning... the above video has some PG-13/NSFW language If you are a gamer (especially FPS-style 3D shooters), you owe it to yourself to stop what you are doing and immediately watch this cool video! It's a live action/filmed "Doom-style" FPS game, and it looks like a ton of fun from both sides of the camera and/or keyboard. You can tell a lot of work went into making this epic game/interactive film, but it surprisingly only cost £900 (about $1,450) to make. We are sure many/most of the folks involved volunteered for the awesome experience, which probably helped keep the costs low. The whole thing was filmed in the production company's backyard, and all I have to say is... you have the coolest backyard EVAR!!!
