Hints:

Clock Tip:
     If you look at the pool table in the Bar Room of the Guest House,
you'll  notice  cue balls reading 12, 6, 3, 9, a clock dial at the end
of  the  table, and 2 cue sticks. This represents a clock; the numbers
represents  the  numbers of a clock, and the cue sticks represents the
hands  of a clock, the shorter hand being the hour hand and the longer
stick being the minute hand.

     For Jill's storyline, it reads 3:45 and for Chris's storyline, it
reads  2:15. What this tip does is that it makes it easier to open the
door  with  the  numbered  key-pad lock in the beehive room. For Jill,
enter  3, 4, 5 and the door will unlock. For Chris, enter 2, 1, 5, and
the door will unlock.

     Note:  The  numbers must not have been played with previously for
trick to work.

Colt Python with unlimited ammo:
     Beat  the game in the ADVANCED mode with Chris or Jill and rescue
everyone  so at the end it says "What a tough guy! You have completely
closed  the  case!" Then it will ask you to save the game. Do it. Then
go  to  load game at the title screen and load the game. Then you will
have the Colt Python with as many shots as you want.

Double Ammo:
     At  the title screen choose NEW GAME then go down to ADVANCED but
don't  choose  it.  While  ADVANCED  is highlighted, hold RIGHT on the
D-Pad.  After  about 10 seconds the color of ADVANCED will change. You
may now start a game with either character.

     From  now  on, whenever you pick up a clip it will have 30 rounds
instead of 15 and the ink ribbons will have six saves instead of two.

Easier Way To Get New Clothes:
     Start  a  new  game  and  highlight Advanced. Hold Right until it
turns  green.  Then select it. Select Chris and when you get the Armor
Key,  go  through  the door by the blue double doors in the main hall.
Head  to  the  room  with the large mirror. Go into the other door. It
should be unlocked. Inside will be some new clothes.

Easier Way To Kill The Plant Boss:
     To  save some time, as Jill, don't go into the drug storehouse to
make  the  V-Jolt.  Instead  just  go downstairs and drain out all the
water  from  the  basement.  Then,  once  you're  done  fooling around
downstairs, head back upstairs and load flame rounds into your bazooka
(assuming you got it) and go into the Plant Boss Room. When you get in
there  fire  at  him  as  usual. It should take about four shots. When
you're  finished and the plant has been reduce to a pile of purple goo
on  the  middle  of  the  floor, run over to the fireplace and get the
helmet  key.  Doing  this should save about fifteen minutes. You don't
have to do this if Barry comes in to save you though.

     If  this doesn't work, do the exact same thing as above, but when
you  get  back upstairs load explosive rounds in your bazooka and fire
at  will.  It should take about four shots. When you do that the plant
should  shrink  itself  and gather itself at the top and bottom of the
room.  Now  exit  the  room,  load flame rounds and go back inside. It
should only take four flame rounds to kill it once and for all.

Hunting Tips:
     To kill Zombies in one shot, let them walk right in front of you.
Then aim high with the Shotgun and fire. Poof! Dead zombies.

     For  acid-spitting  zombies, let them get pretty close, then fire
three  steady  shots  with  your  Beretta. This will save you a lot of
ammo.

     To kill spiders quick, here's what to do. If you're Jill, arm the
Bazooka with Flame rounds. Then when you encounter a spider let it get
pretty close (or if you like, when it's ready to bite you), than fire!
This  works  only  agaist  medium-sized  spiders. You can try the Acid
rounds, but it might take a shot or two more.

     For Chris, if you can pick up the flamethrower, use it agaist the
huge spider. Just fire until it's dead.

Remove Emblems:
     To  remove the emblems from the Doom books, examine the books and
turn them on their side with the pages facing you. Press X to open the
books and retrieve their emblems.

Rocket Launcher with Unlimited Ammo:
     Finish  the  game  with Chris in under three hours, then save the
data  to  a  memory  card.  Start a new game using the saved data,then
check  Chris's inventory. You'll find a rocket launcher with unlimited
ammo.

Save Some Ammo:
     When  playing  as  Jill  the  first  Zombie you come to is in the
corridor  over  Kenneth's body. As soon as the Zombie starts coming at
you,  run  into the dinning room where Barry is. Barry will ask what's
wrong,  and then kill the approaching Zombie. This will save you a few
rounds of valuable ammunition

Double items:
     Highlight  the  "Arrange" option on the game mode screen and hold
Right  until  the  pointer turns green. Begin game play and double the
normal  amount of items, including ink ribbons and ammunition, will be
available.  Note:  This  does  not  effect other items, such as health
sprays or herbs.

Reset game:
     Pause  the  game  during  play and press Start + Select. The game
will reset and return to the main menu.

Controller configuration:
     Press Select + Start during game play.

Unlimited magnum:
     Select  "Arrange"  mode and complete the game as either character
in any amount of time. The unlimited magnum will be available when the
game  is replayed. This weapon makes it easier to complete the game in
under  three  hours  for the unlimited rocket launcher, at which point
both weapons will be available for another game.

Killing Plant 42:
     Chris  can  save  ammunition  when fighting Plant 42 by using the
combat  knife.  Only  about  a dozen hits with the knife are needed to
kill it.

Auto aim:
     Instead  of  having to turn around manually to shoot the zombies,
hold  R1  and  your  character will automatically aim their gun at the
nearest zombie/danger. Tap L1 while continuing to hold R1 to have your
character re-adjust his or her aim. This is a much faster way to fight
quick enemies, and saves ammunition from missed shots.

Logging onto the computer:
     To log in to the computer in the lab, and unlock the areas B1 and
B2, use the following passwords.

1st: John
2nd: Ada
3rd: Mole 

Getting the Star Crest:
     Go  to  the  hall  with the numerous paintings and crows. Put the
switches  behind  the paintings in the following order: new born baby;
infant; lively boy; young man; middle-aged man; bold looking old man.

Saving herbs:
     If herbs are not needed immediately when found, take some time to
transport them to one of the Boxes. If you need to use them later, you
will know where to find them.

Save ammunition as Jill or Chris:
     Stand  behind  the statue in the room above the dining room. When
the  zombies  come up on the other side, they will try to walk through
the statue leaving you free to knife them to death.

Fight Bravo Team member Forest:
     When playing as Chris, just go to the balcony on the second floor
of  the  mansion.  Approach  the  corpse  (Forest).  There should be a
mansion key. Try to pick it up. Forest will attack you.

     When  playing  as Jill, go to the room with the first zombie from
the  dining  room.  Then, go back to the main mansion room. Barry will
tell you to search the hall. Do that, then go directly to the balcony.
If  done correctly, Barry should not be there. Go to Forest and try to
take  the  key. There should also be a grenade launcher located there.
You  can  use it to kill Forest faster. However, if you try to pick up
the  mansion  key  Forest  will attack you. Note: :Forest is harder to
kill than regular zombies.

Get all weapon and all ammos with all maps for current misson:
     Get  a  knife  and use it to attack one of the zombies or enemies
and  use  the weakest gun you have to shoot them dead after your first
hit with the knife. Go to your weapon list and trash out everything as
in  throw them away and go pick up another weapon and check the weapon
list  and  all  weapons  in  that stage or mission is there. Unlimited
ammos goes with it.
