To change Leon's or Clair's costumes, choose "normal" skill level, start the game, go to the Racoon PD
gate (right after the bus.)
DO NOT PICK UP ANYTHING ALONG THE WAY.
After the gate, go down the stairs that you see in front of you, and you'll see a yellow vested zombie that wasn't there before: pop a couple bullets in him and when he falls down, go up to him and pop a couple more into him. Reach down after he's dead and you'll receive a "special key". Bring the Key to the dark room and use the key to open the police locker.

How to defeat William (first time) easily
You encounter William twice in the game, and face 3 of his stages. You face him in his second when you are going to the lab, you need heavy guns, Claire should use the grenade launcher (loaded with acid and flame rounds of course), because the spark shot has too much recoil and a limited range, so you'll end up using more health items than needed, and Leon should use his Custom shotgun and a little magnum wouldn't hurt, though you really don't want to use more than a clip. put distance between you and William so you can plug him from a safe distance, and stay to a side of the walkway, so if he gets close, you have a change to juke him and run along the other side, repeat as necessary. (Leon can even use his Custom handgun, if you found the parts, on automatic)
How to defeat William (last fight) easily
In Scenario A, you face William again at the room where you call the large elevator. If Claire found it, use the
submachine gun and he's as easy as pie, when he transforms, whip out that grenade launcher and put some grenade rounds right into that big mouth of his, for Leon, use that flamethrower, or if you decided to take it, the submachine gun for the first round, when he transforms, finish off the flameshrower on him and use that Custom Magnum if you got it, otherwise the regular magnum or upgraded shotgun work well, but he bounces around a lot, so make sure you bring plenty of health items, and when he goes into his transformed stage, he can hop up on the tops of those tanks, when he does, run around, so he doesn't smack you when he jumps off.
