Leech Hunter, Collecting Leeches
While playing the Leech Hunter mini-game, kill everything in the
Mansion, Train Tunnel, and Basement before picking up any of the
leeches. Once you pick one up, you cannot put it down. Each player
can find a maximum number of 50 leeches (100 total leaches in the
game). One item slot can only hold 10 leeches only -- be careful.
Once you get 95 leeches, zombies will start to come back to life.
Collect the leeches in the mail hall, dining room, and the second
floor room where you use the MO disc last so you do not get killed.
An easy way to complete Leech Hunter mode is to go through and
kill all the enemies first, then return and collect the leeches.
Collect the leeches in the Basement area first to avoid the
risk of revived Zombies.
Leech Hunter, Extra Submachine gun ammunition
As soon as Leech Hunter starts, grab the first leech you see and
run out. This will give you a clip to the machine gun.
Save ammunition on first Leech zombie on the train
After the sequence with the first Leech zombie, just go back
downstairs and the intermission sequence will take place again.
Avoid Leech Zombie explosion
When you fight the Leech Zombie, its legs will swell up at the end
and explode, hurting and often killing you or your partner. There
are three ways to avoid this. First, just leave as his legs are
swelling but before he explodes. The second is to use a Molotov
cocktail on him, which will light him on fire and melt into a
puddle of slime and leeches. The third way is to kill him while he
is still in "human" form, which is best done with the magnum and
has the end effect as the Molotov cocktail.
Resident Evil 2 areas
When you eventually get onto the moving cable car, after Billy is
taken over the railing by an ape, go across the ravine and head up
the pair of steps. You will enter a big room with a metal floor.
This is the same area in Resident Evil 2, where you call up the
platform train to head down into the main factory (and where you
fight a stronger version of the William Birkin mutations). If you
go towards the bottom of the screen and go down the lift and into
the back room, you will find a television screen with a picture of
a Tyrant. This is the same room where you see Mr. X walking
towards the camera before smashing it. If you call up the platform
and take it down, you will enter the factory sub-levels and walk
into the room where Leon/Claire had to carry Ada/Shelly to the
security room.
Hard mode
Use the following tips to complete the game in hard mode.
Use Billy all the time. He can take much more damage
than Rebecca.
Leave Rebecca in the main hall. She just uses up
ammunition and first aids. However, bring her the plants
to mix for you.
Use a custom handgun, or if you dare, a knife to kill
the tyrant. It is easy to run circles around him and
shoot him in the head, or use the knife. It may require
about 30 shots with the custom handgun to kill one.
Use the Magnum ammunition for the last Boss only.
Do not use the Pump Action Shotgun. It is weak. The
Hunting Gun does more damage. Get it on the train and
keep it.
Use Herbs only if you are really hurt bad.
Use Fire Grenades on the Leech People.
Use your Molotov Cocktails on the final Boss' third
form, Tyrant, or Leech People.
Sometimes you can run pass the hunters and out the room
without wasting ammunition, such as when you get the up
key. The same goes for the Leech People. They are too
slow if you use one person to run past them.
Fountain circle puzzle
When you get to the fountain circle with the six animal statues on
Disc 1, use Billy to light the statues in the following order
Deer, Wolf, Horse, Lion, Snake, Eagle.
Pause timed puzzles
Try to change to your partner during a timed puzzle. Remain idle
at the error message to give yourself more time to study the puzzle.
Piano room
When you get to the piano room, make sure you have both characters
with you. Have Billy play piano. A door will open by the bar. Have
Rebecca go in and take the battery. The door will close. Have
Billy play piano again and the door will open.
Better shotgun use
Once you get the shotgun, do not use it. Instead, leave it in the
room with the scale you put the two figures on. Find, but do not
pick up, lots of shotgun ammunition. After you save her from the
pit, give all the hand gun ammunition to Billy and collect the
shotgun ammunition. If you get it all, she will have about 60
rounds, which is much better than using two hand guns.
Safer and faster shotgun reload
To reload the shot gun faster, press Y to go to the item screen.
Combine the shotgun ammunition with the shotgun. You will be able
to attack again without having Billy or Rebecca reload and waste
precious time.
Extra inventory slot
When playing as Billy with Rebecca as the alternate character,
have Billy hold all the pistol ammunition for both characters and
keep her gun fully loaded. This gives you one free inventory slot.
Dail door number puzzle
Enter "4863" on Disc 2, where the cable car is located.
Chess puzzle
Look at the smaller chess board on the desk in front of the big
one. Arrange the big pieces the same way. The difference is the
only white piece by itself. Use Billy to push it down, to the
right, and finally right in front of the black piece. The desk
will now open.
Brake system puzzle
The main code is 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 7 + 2 = 81. This
should activate the brakes for the train.
The second code for the brakes is 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 +
5 + 6. This will start the brakes.
Alternate costumes
Successfully complete the game with any rank under the normal or
hard difficulty settings. Start a new game. A Closet Key will
appear in your inventory. Use it to unlock the closet in the room
where the Hunting Gun was first found to access new costumes for
Rebecca and Billy.
Completion bonuses
Successfully complete the game with a "B", "C", or "D" rank to
unlock the Leech Hunter mini-game.
Successfully complete the game with a time between 3:31 and 5:00
for an "A" rank to unlock the Submachine Gun and Leech Hunter mini-game.
Successfully complete the game with a time of 3:30 or faster for
an "S" rank to unlock the Rocket Launcher, Submachine gun, and
Leech Hunter mini-game.
To a rank after completing the game it must be played under
the normal difficulty setting. You will not get ranked under the
easy difficulty setting, but can still unlock the Leech Hunter mini-game.
One hit kills
When playing as either Rebecca or Billy and you get bit by a
zombie, move the character opposite of your main character
directly behind the one you are controlling to have him or her
shoot the zombie in the head and kill it in one hit, while the
zombie deals you no damage. You must have pistol equipped to
save ammunition for a one bullet kill.
