Do not pick up any items or weapons on your way to the police department. When you reach the police department, go down the stairs outside, waiting there, there will be Brad the helicopter pilot from the first resident evil, only now, he is a zombie. Either charactor can do this, but only in the first scenario. He will be harder to fight than any other zombie, so be careful. It will take somewhere around 30 handgun bullets to kill him. When or if you kill him, you can pick up a key off him that will allow you to access the lockers on the eastern side of the police department by the stairs. Note: The only way this code work is in original mode on easy or normal. Do not choose arange mode.
To get the Shotgun parts for Leon reach the part where you team up with Ada at the umbrella building. In the first room that looks like a Y go to the left end of it. There will be Shotgun parts.
To get the handgun parts, in the place where Leon gives Claire a radio there is a drawer. Use a small key or the lockpick to open it. Inside are the handgun parts.
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.
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.
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.
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.

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 bullets. Alleyway past the basketball court Go past the zombie-filled basketball court until you find a van. Search the back of the van and to receive hand gun bullets.

The hall behind the main R.P.D. police office (with the safe) Look for an unmoving zombie lying face-up on the floor and search it for hand gun bullets.

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.
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.
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.
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.
