This is the Kickstarter for Blood Sport, an immersive gaming system that takes some of your blood intravenously whenever you get shot in-game. Blood Sport is being developed with the hope they can eventually organize gamer blood-drives, where everybody gets together to game for a good cause. Basically, the system works by rerouting the signal that would make a controller's rumble-pack rumble to turn on a blood collection machine instead. But what if my controller is rumbling even though I didn't get shot? Maybe I'm just crossing some rough terrain! Unfortunately, I've never been able to give blood before because I'm a passer-outer, but I would be willing to give this a go. Maybe it'll take my mind off what's happening long enough to make a worthwhile donation. But please -- be ready to yank the cord on the XBox before it sucks me dry.
Keep going for their Kickstarter video.
Thanks to Taran, one of the creators of the project. Wow, and to think all this time I've just been stabbing my opponent whenever I lose and soaking up their blood with an old t-shirt.
