Things You'll Need
Instructions
Boot up your PlayStation with the Gameshark peripheral attached to your console as well as the Twisted Metal 2 game loaded onto the drive. When the Gameshark menu appears, select Twisted Metal 2 from the list and add a new code.
Enter the code 8003434A 0E0E. Save the code, then activate it. A star will appear next to your code indicating that it will be applied when the game boots up.
Start up your Twisted Metal 2 game and enter the character selection screen. When the screen loads, select Roadkill, the first person on the list. Choosing any other character will crash the game. Once the game starts up, you'll automatically unlock and begin playing as Dark Tooth.
