Rifle

The C.P rifle is a gun that does not run on ammunition, but batteries. It is located 
in the sewers. Go to where the plant and laboratory is located. You can find it in 
the room that has creatures locked in a chamber. It is in the chamber that is open. 
Once you get it, the creatures in the other chamber are released. Use a different 
gun to kill those zombies in order save your batteries for Morpheus.

Assault Rifle And Shells

Start the game under the easy difficulty setting. On the 2F, go into the kitchen. 
There will be a door directly across from the entrance. Go into it and enter the 
open room. There will be an assault rifle with 100 shells and 100 extra shells next 
to it. This awakes the zombies in the freezer. To kill them easier, go back into the 
kitchen for a few seconds, re-enter, and get ready to fire.

Defeating Morpheus

When Morpheus is not a giant slug, use your grenade launcher or C.P. rifle. You 
must move constantly. Shoot him once or twice with one and move. Zigzag 
between the poles and avoid Morpheus' quick hand. If, however, Morpheus is able 
to hit you with his hand, after four or five hits, he will do a backflip away. When he 
does this, run immediately and heal with a Green Herb or other item.

Easy Map Access

Press Select to get to your map without having to press Start and searching. 
Pressing Select also gives you a better view of the map, showing where you are, 
which rooms are locked, which rooms you can go through, etc.

Pause Game Play
To stop the game clock, enter the items screen.

Defeating Torpedo Kids

Killing the torpedo kids is very easy. Take out your shotgun and shoot them. 
Although they are fast, all you have to do is shoot within reason, about a 
centimeter or two off, as the shotgun shoots out multiple shells at a time.

Defeating Giant Morpheus

To kill Morpheus when he becomes a giant slug-type creature, keep shooting at his 
eyes. Try to develop a rhythm of where his head moves. As you hit his head, he 
will move backwards, allowing you to defeat him.

Handgun Ammunition
Ammunition for your handgun is located in the lounge and other places where you 
save your game.

Keys
The first key you need is located under the corpse in Room 101 2F. Press X or 
Circle. After you go into the very next room, a female zombie will come alive. This 
is the first zombie that you kill. This key is to one of the big doors out in the main 
beginning hallway when a new game is started. The second key is located in the 
VIP Room 2F. This key unlocks two of a floor's electronic locks.

Easy Handgun Kills
To kill the zombies or other creatures quicker with the hand gun, take an extra 
moment and aim at their head.

180 Degree Turn
Tap Down(2) to make a quick 180 degree turn. This is extremely useful in certain 
circumstances.

Walk In First Person (shoot Mode) 
Hold A or B in shoot mode and press Up or Down on the D-Pad at the back of the 
gun to sneak. As usual, holding A allows you to sneak with the same control 
system as if you were running. Holding B allows you to sidestep instead of turning.

Defeating Bosses
To easily kill Bosses or larger zombies, shoot them with the Magnum.

Defeating First Non-zombies

The first creatures resemble walking frogs. They are fast and can jump. Try 
shooting them with a shotgun, then continue while they are down. If you are out of 
shotgun shells, use the handgun and shoot them once and run. Once they begin 
chasing you while you are using a handgun, get a good distance and begin 
shooting them again. However, run when they are about ten feet from you.
