 Alternate uniforms
 
 Start a game on the normal difficulty setting. Then, go 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 and go to the dark room to open the lockers with alternate
 uniforms. Claire has a single alternate uniform, with a quick
 shooting revolver. Leon has two alternate uniforms, one of which will
 allow him to shoot with one hand. 
 
 Auto-aim
 
 Select "Options" from the main menu or press Select while playing a
 game. Enter the "Key Config" screen, select "Type C", then select
 "Exit". The quick auto-aim feature should now be enabled. Hold R1 to
 get Leon or Claire to pivot and aim at any zombie they see, and press
 L1 while holding R1 to change targets. Note: You still have to hold
 Down to aim at crawling zombies and Up to aim at higher targets.
 
 Film D
 
 Search the desk on the left side of the S.T.A.R.S. office. The phrase
 "Its trashed someone must have searched it" will be displayed.
 Repeatedly search the desk approximately fifty times until a roll of
 film is found. Take the film and develop it in the photo lab to see a
 picture of Rebecca in a basketball uniform. 
 
 Shoot the screen
 
 While playing Leon's scenario, take the infinite ammunition shotgun
 and go to the roof where the helicopter crashed. Stand near the door
 leading inside, and make sure that a close-up view of Leon appears.
 Then, aim the shotgun at the screen and fire. Bullet holes will now
 appear. Note: This may also be done at any location where Leon can
 aim at the screen with the shotgun.

 Alleyway past the stairs of the gunshop

 Mixing herb power-ups
 
 The herb power-ups can be mixed using the "combine" command for
 varying, but very beneficial results. This will also save storage
 space for holding puzzle items. Here is a listing of some herbal
 combinations and the outcomes: 
 
 1 green herb + 1 green herb = 60% health recovery
 
 1 green herb + 1 blue herb = 20% health recovery and poison antidote
 
 1 green herb + 1 red herb = Full health recovery
 
 3 green herbs combined = Full health recovery
 
 1 green herb + 1 red herb + 1 blue herb (in that order) = Cure-all
 (full health recovery and poison antidote)

 Hints
 
 Final stage bonus room
 
 The final stage has a bonus room that can be entered through a long
 but easy process. In the first scenario, have Leon or Claire use the
 red lab key card to enter the room with the giant flying moth. Kill
 the moth. Find the keyboard attached to the wall, kill the larvae on
 it and type your name in on the keyboard as "GUEST". Register your
 fingerprint. Go to the first floor of the lab and find the thumbprint
 reader panel. Use your fingerprint, and the panel should then ask for
 a second "fingerprint verification." Complete the game, and save the
 second scenario to any file. In the second scenario from the game you
 have just played, go to the final stage. Find the room on the first
 floor of the lab where wriggling plant vines are blocking the vent.
 The red lab key card should be there. Take it and go to the moth room
 with the keyboard. Enter your name as "GUEST" and register your
 thumbprint. Finally, go to the first floor and find the thumbprint
 reader. It should ask for the "secondary fingerprint verification."
 Do it, and the bonus room to the right of the panel should be
 unlocked. Look for a special weapon inside.  
 
 Safe combination
 
 The combination to the safe in front of the chief's desk at the
 police office, with all the zombies, is 2236. Open it to find shotgun
 shells and a map. 
 
 Easy gator kill
 
 When fighting the gator, and he starts coming towards you, go and
 inspect the yellow light on the left wall. Then, the light will fall
 off and the gator will eat it. Now while the light is in its mouth,
 shoot it and the gator will explode.
 
 Tyrant's ammuntion
 
 In Leon or Claire's second scenario, the player will constantly run
 into a giant super zombie called Tyrant. Every time a Tyrant is
 defeated, the player can steal his ammunition: Shotgun shells or
 magnum bullets for Leon, and grenade rounds or bow gun bolts for
 Claire.
