New Outfits
All you have to do is play the game at 'Normal'. Next, do not pick up anything during Scenario A's run to the Police Station. If you did it right, then the two zombies in the yard before the police station will be gone and replaced with Brad Vickers in the tunnel. He uses a lot of bullets. So before confronting him, go inside and grab the package of bullets off the counter in the station at where the computer is located.
