- 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.

Successfully complete either character's first and second scenarios in less than three
hours. Then, play the game again with the other character, and successfully complete their
first and second scenarios in less than three hours. Play the game a third time and
complete either character's first and second scenarios again in less than three hours.
Note: The game must be saved less than twelve times during each of the six
scenarios played and bonus weapons must not be used. Tofu is a piece of tofu (food) that
must reach the second floor of the police station from the sewer with just battles and no
puzzles. Tofu can not use any weapons other than a knife.

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.

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.

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)

Successfully complete level 2 of Extreme Battle/Survival mode.

The following locations behind and within the police station in the first scenario contain
hidden ammunition caches:

 - Alleyway past the stairs of the gunshop

Turn towards the trashcans opposite the blue dumpster and search them for hand gun

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.

Beat the game with Leon, then save the game. Then, play Claire's second scenario, beat the
game, and save the game.

Select "Options" from the main menu or press Select while playing the 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.
