Extreme Battle/Survival mode:
Select the "USA Version" option and begin game play. Complete Leon's first scenario and save the game. Then load, complete Claire's second scenario in "USA Version", and save the game. The typewriter will type "???" instead of Leon's second scenario. Load that saved game to start Extreme Battle mode.
Play as Ada Wong:
Successfully complete level 1.
Play as Chris Redfield: Successfully complete level 2.
Alternate uniforms: Complete either character's first and second scenarios in less than three hours. A zombie in a uniform will appear after both missions are completed to confirm correct code entry. Load the saved game and begin the first scenario by going 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 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.
Alternate uniforms (2): Select original mode at the game selection screen. Then, go to normal game. Play through the beginning of the game without picking up any items (using the unlimited ammunition code is recommended). After reaching the police station, go down the stairs right next to the gate. You will see a zombie in a yellow vest (Brad Vickers from Resident Evil). Kill him and check the body for a "special key". Take this key and immediately head for the film developing room (dark room). There is a locker to the left when you first walk in. Use the key and Leon will get either an R.P.D hat, blue "wife beater" and green pants, or a bikers jacket with a skull on the back and black leather pants. Claire will get a cowgirls outfit and a Colt S.A.A (uses handgun bullets, but is faster and more powerful)
Unlimited weapons: Complete either character's first scenario without saving the game in under 2.5 hours with an A or B ranking for the special rocket launcher. Complete either character's second scenario without saving the game in under 2.5 hours with an A or B ranking for the special gatling gun. Complete either character's second scenario without saving the game in under 3 hours with a A or B ranking for the special machine gun. The special weapon will appear in the next game after the first chest is opened.
Hunk scenario: Complete Claire or Leon's second scenario saving less than twelve times with a end time of under two hours and thirty minutes. Hunk is a soldier that must reach the second floor of the police station from the sewer with just battles and no puzzles.
Tofu scenario: Complete either character's first and second scenarios in less than three hours. Play the game again with the other character, and also 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 saved less than twelve times during each of the six scenarios played and unlimited 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.


The following locations behind and within the police station in Scenario 1 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.
Dark Room: Search the filing cabinet along the wall (next to the storage box) for hand gun bullets.
S.T.A.R.S. office: Check behind the "trashed" desk for hand gun bullets.
Hall with the stairs to the basement: Search the mop bucket leaning against the metal shelves behind the stairs.
Night Watchman's bunk room: With Leon, search the lockers for shotgun shells.
Briefing room (with the chalkboard): Using Leon, go to the room where the red jewel was hidden in the painting and search around the middle of the junk pile of art at the far end of the room.
The hall with the crows: Search the man "that was pecked to death" twice for 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.
The hall with the filing room (near the beginning of the police station stage): Check the dead zombie lying on the floor.
Filing room (with the two sided filing lockers in the middle): Using Leon, check the middle filing cabinets for shotgun shells.
Party room (with the last surviving police officer): Search the cabinet where you talked to the last surviving police officer.
Statue with second red ruby: Have Leon or Claire search behind the statue with the second red ruby.

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 = Full health recovery
1 green herb + 1 blue herb = 20% health recovery and antidote
1 green herb + 1 red herb = Full health recovery
1 green herb + 1 red herb + 1 blue herb (in that order) = Cure-all (full health recovery and antidote)
3 green herbs combined = Full health and more

Unlimited ammunition:
Begin game play and press Select to display the options screen. Select the Key Config option, then hold R1 and press Square (ten times). The word Auto will turn red to confirm correct code entry.
Stronger weapons: Select the "Arrange Game" option at the main menu and play as a rookie. When you first start as either character, you will have the submachine gun with unlimited ammunition. When you get to the police station, you can find aid sprays, a shotgun, some ammo, a gatling gun with unlimited ammo, and a rocket launcher with unlimited ammo inside any box.
Auto-aim: Select "Options" from the main menu or press Select during game play. Then, enter the "Key Config" screen, select "Type C", and 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 is held to change targets. Note: You still have to hold Down to aim at crawling zombies and Up to aim at higher targets.
Ada Wong picture: 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 Ada Wong in a basketball uniform.
Shoot the screen: While playing Leon's scenario, take the unlimited 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. Aim the shotgun at the screen and fire. Bullet holes will appear. Note: This may also be done at any location where Leon can aim at the screen with the shotgun.
Easy crocodile battle: When fighting the crocodile in the sewers, simply run back to the door on the opposite end of the corridor and wait with the shotgun equipped. Just shoot it one time and it will crawl off.
Using the crank:
Enter the copier room that requires the precinct key. Go to the silver "ladder" and push it forward. Stand on it to find the crank. Go to the room on the third floor with the "engines". Go to the right to find a square hole. Use the crank and stairs will appear.
The statue with the ruby in its hand: Push the gray statue to the mark in the wall on the right. Push the red one opposite to the gray statue so that "Their Gaze Upon Them Will Release The Red Soul"
Tyrant's ammunition: In Leon or Claire's second scenario, the player will constantly run into a giant super zombie called Tyrant. Every time he's defeated, the player can steal his ammunition: Shotgun shells or magnum bullets for Leon, and grenade rounds or bow gun bolts for Claire.
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.
Extra ammunition for Leon: When playing Leon's scenario and get the custom parts for a gun, do not use them immediately. Instead, first use all of that ammunition, and then combine them with the custom parts.
Hanging birds on the wall: Shoot the birds with the crossbow to pin them against the wall.
Zombies in shed: In the little shed with the valve handle, do not go through the next door. There will be two zombies coming through the door as you do. You will then have to shoot them.
Special weapons: Use the Mac11 for fun, as it is not a good or fast gun. Use the Rocket Launcher for blasting dogs,lickers and monsters. If you are fast, use it for spiders and zombies. Use the Gatling Gun to kill anything.
Easy crocodile battle: As you are approaching the crocodile battle, there is a gas cylinder on one of the walls. You can press a button and release it, but this cannot be done until the crocodile attacks. When it attacks, run down the hall until you reach the gas cylinder. Release it and continue to run from the crocodile. Wait for it to come on screen with your gun aimed in its direction. As the crocodile comes around the corner, it will have the gas cylinder is in its mouth. Shoot it until the cylinder explodes and takes off the top of the crocodile's head.
Easy Zombie kill: Begin a new game with Leon, with high violence, and any blood color. Get through the crowd of zombies at the start. Go into the gun shop and wait for Robert (the shop keeper) to get eaten by zombies. Get the Shotgun and wait for a zombie to get close enough. Aim up and shoot its head off. Aim down and blow its leg off. Note: This trick also works with the Magnum, Custom Magnum, and Custom Shotgun. Sometimes when you shoot a zombie close to the waist, its torso will fall off.
Shotgun or crossbow: When playing as Leon go to the gun shop with the man. He will almost shoot you. After he dies because of the zombies, kill them. Then go up to the dead man and press Action. You should get a shotgun. If playing as Claire you will get the crossbow.
S.T.A.R.S. members group photo: There is a picture of the S.T.A.R.S. members in the RPD. Go to the S.T.A.R.S. office in the second floor of Police Station. Look into the picture between Weskers' desk and the trophy shelf.
Upside down flag: Go to the police station and enter the room where the police have meetings, and where you have to light the fireplace with the lighter to get the red jewel. In the room where the soda machines are is a flag. It is an American flag that is upside down.
Blue Coke can: In the same room where you get the Hand Gun Parts to enhance your weapon, near the door is a soda machine with a blue Coke can on the front of it.
Easy Scenario A Boss battle: Use the following strategy when fighting the last Boss of either A scenario. Get in one of the corners and use the machine gun to continuously hit him. The speed at which it fires almost stops him in his tracks. If your character gets hit, heal then run until reaching another good position to use the machine gun. The battle lasts approximately one minute using this technique. Another strategy is to use the rocket launcher to kill the Boss in a single shot. However, less points are scored with that method.
Checking Zombies: If you are not sure if a zombie is dead, walk up fairly close to it (but not so close that they start chewing your ankles) and simply back up. If the Zombie is alive, the character will do a wary backup move instead of the standard backup done when there is nothing there.
Detecting enemies: In order to tell whether or not there is an enemy that you can hear, but cannot see (off screen), turn in the opposite direction of where the enemy may be, and press Aim. If there is an enemy present, your character will turn around and aim in the direction of the enemy. If nothing is there, your character will just aim in the direction you are facing. This also is useful if you are not sure if a taken down zombie is actually dead.
