 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.

 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)

 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.
