If you use a dagger on a zombie, take out the shotgun aim up and blow and blow it's head off. Go over to the zombie and pick up the dagger you use. this only works with daggers. This will save you lots of daggers if you do this a lot.

this is more of an easter egg than tip but..... ok in the labs while on the computer login with the information

NAME:john
PASSWORD:ada

then select B-2F and for the password type MOLE (that was the password for the original game) you can hear a funny voice instead of the normal wrong sound.....

ok first do the grenade glitch (jill only) with incenadairy grenades then when you kill a zombie equip your grenade launcher with incenadairy grenades and aim down on the zombies corpse and shoot it.Hopefully you hit it and it will catch on fire then when you come back to that room that zombie will have vanished just like if you used kerosine and a lighter

As Chris get the enemy to bite you and use the flash grenade defence item and watch his head go boom for an instant kill, which can save some much needed shotgun shells.

Jill can try something similar using the taser but it won't kill them instantly but it does take off like 10-50% of their health.

Don't try this with the knives though as the damage they cause is insignificant.

when a zombie encounters you aim your gun at its head saving bullets for another zombie.

A nifty fact that should not be overlooked is the power of the self-defense gun, which ranks as definetly one of the strongest non-explosive weapons in the game. True, it can only be fired once and is non-reloadable, but it's one-hit capacity is invaluable. With a direct-hit potency of up to four regular blasts from the magnum (not Barry's), it can take out every enemy in the game with one shot, including bosses and Tyrant during your first encounter. Use this weapon wisely - it can end a boss battle very quickly, in your favor.

If you are low on recovery items and health shoot the zombies in their legs with a shotgun shell. After this you can take an endless amount of bites in your leg! It works for all resident evil titles! HAHAHAHA! LET THE ZOMBIES DIE!!! MOOSE

This is a step by step guide to getting this glitch to work. Follow these instructions or it will fail.

Requirements: You must have the grenade launcher and two types of ammo (e.g., Grenade Rounds, Incendiary Rounds)

1) Put all items in item box
2) Put Grenade Launcher in upper-left item slot
3) Put Incendiary Rounds in upper-right item slot
4) Close box
5) Open inventory
6) Equip Grenade Launcher
7) Open box
8) Select Incendiary Rounds from inventory
9) Press A twice
10) Move cursor to Incendiary Rounds inside box
11) Press A twice

The amount of Incendiary Rounds in the Grenade Launcher will now increase. The number value will be graphically glitched. Close the box and open inventory to fix that. I assume the value exceeds the possible amount, so the game automatically reduces the rounds to 240 to prevent data corruption. Enjoy.

This also works for other types of grenade ammo... But why you'd want anything other than Incendiary Rounds is beyond me.

First of all, you have to do this with jill. When all the beginning cinematics end, and you are in the dining room, go back into the main hall. Wesker will say " I am counting on you to find out what that gunshot was." At this point, you will go back in, but try to go back into the main hall AGAIN. Barry will talk about jill having cold feet, and after that occurs, go north and talk to barry. When you are done talking to him, head towards the ticking clock on the west side, and there will be your cinema.

Beat the game with Jill or Chris and save. You'll get a new background on the main menu. Choose "Once Again" and you'll find that you can now choose a new difficulty setting.
