The square button for Wanted: Weapons of Fate on the PS3. Does absolutely nothing. I've died so many times because I'll be running up to some guy with intent to knife him in the face, the "press circle to fuck this guy over" icon will appear, and then the guy will shoot me in the balls and kill me because I was wailing on the square button the whole time. Seriously, who designs a game in which one button has absolutely no function? They could have at least let you use the knife with the square button and saved me some embarassing deaths.
