Not satisfied with using a normal controller with Resident Evil 4? Why not try out this dedicated blood-splattered chainsaw joypad currently available for pre-order from Lik-Sang. According to the description text, "holding it in your hands for sure makes you feel like a man." Do you think they're joking?
Apparently, it comes with a sound chip to mimic the noise of a revving saw, but I don't think it has a motion sensor to translate your wild manly thrusts into game movements...
