Just picked up a used copy and am thinking about grabbing a radnet code. Do you have to enter the code before you start the game to use it or can it be done mid game. The opening screen says enter code or skip forever. --- PSN GUB-MENT86
Just buy it and enter it in. Save yourself the trouble. Try to get the mutation rewards as soon as you can because they help but some of the mini games can't be accessed until you reach the other zones.
