A game peripheral that involves draining your blood every time you lose health in a game?
Some of you might call me crazy for saying this, but in my opinion, if that's not a truly hardcore way to play a game, I don't know what is.
Though I dread to think what would happen if I played Fallout 3 or New Vegas with that thing on me, if I took a missile to the face in-game, 2 things could happen;
1) the blood pack containing my blood might explode, leaving more blood on me than a Dragon Age character.
2) I might get into hemorrhagic shock or die, after call, do you know how much blood you can lose getting hit by a missile? I think I know only this answer; alot.
