Those old arcade machines that you used to have to hold onto to win, just like in bond but at a much smaller scale and target at less skin. A bullet hits you from the left and zap, your right hand palm gets a micro second sharp vibration shock, obviously with a slider for intensity. I think it'd be sick. There's a lot they could do, perhaps add it to the face buttons and this would also enhance games, keep you on your toes in a shooter and train the brain that getting hit is a bad thing, it'd encourage more tactical play. I'm playing Xdefinlant right now and I'd be less likely to throw myself at bullets if I was gonna get a shock. Perhaps it's going to far with that one but other stuff I'd like to see the face buttons be made maliable and get the same treatment as the triggers, I'd reckon that'd be more impressive vibration wise and back to good old push sensitive buttons too.
