Alternate uniforms
Start a new game with Leon and choose your settings to: red blood color and normal difficulty. Begin the game, and advance past the opening sequence. Do not pick up any items and try to avoid using your handgun bullets (you only really need them for the zombies in the bus and the zombie with the key - avoid the rest of the zombies). Get to the police station gate and go to the lower level stairwell. Outside you should see Brad Vickers (from Resident Evil 1 and 3) as a zombie. Use the rest of your clip on him. If he is still standing after that, run into the police station and get the handgun bullets on the desk near the computer, then go back outside and finish him off. Check his body to find a Special Key which will allow you to change clothes in the Dark Room (where you develop film). Leon has a leather jacket with skull emblem and an old S.T.A.R.S uniform with a baseball hat and Claire has a leather suit with a fast firing pistol called the Colt SAA. Another way to kill the zombie easily is to go up close and shoot his legs to make him fall forward, Then allow him bite your leg and you will crush his head. However, only do so if your condition is at Fine or Caution. If you get hurt by the zombie, get the herb in the garden at the top of the stairwell. This trick allows you to get the uniforms without completing either scenarios. The only difference is if you complete the game you see a short sequence that says "Do not pick up any items at the police station!".
Complete either character's first and second scenarios in less than three hours. A zombie in a uniform will appear after both missions are completed to confirm correct code entry. Load the saved game and begin the first scenario by going to the police station without collecting any items. Quickly move past the zombie that appears in the alley near the police station. Collect the shotgun, then kill the zombie. Take the special key from the zombie's body to open the lockers with alternate uniforms. Claire has a denim jacket, with a quick shooting revolver. Leon has two alternate uniforms (a leather jacket with skull emblem, or a tank top and baseball hat), one of which will allow him to shoot with one hand.
