How you get black suit in spidr man 3 for PC

There are 2 ways to do so. The first is to wait till you get to a bit about three quarters through where you get it auto, and the second is to beat the game. After you beat the game go to playable characters and then click Black Suited Spiderman it will let you play the game a second time with a black suit for the whole game. F-U-N :)
