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.
Defeating 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 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 also 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.
New Clothes
If you complete the game and rescue everyone then you will be awarded a secret key. To do this:
"There is an outfit that fits you perfectly, do you want to put it on?"
Click "Yes" and your characters' clothing will change.
Partially eaten Kenneth
Start a new game as Jill. After Barry and you enter the dining room, return
to the main hall. Wesker will tell you to investigate the gun shots. The
game will return to the dining room. Turn back around and try to go back
out the doors. Barry will say "Lost Courage already? That's not like you."
Move to the blood stain and look at it. Barry will say his usual thing.
Then, go over to the grandfather clock. As soon as you do this, a zombie
will come out the door. Barry will kill it. Return to the main hall and
get the lockpick. Now, go back to the room where Kenneth was being eaten.
He has no clips and half of him is gone. The game is supposedly easier now.
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
For unlimited use of the Rocket Launcher finish the game within three hours. After the credits roll you'll see a rocket fly by. Wait for the game to restart, then choose to play on. You'll start the new game with a rocket launcher!
V-Jolt
Enter the room with the number pad in the dormitory. To create V-Jolt mix UMB No. 2 with water to create the No. 3 chemical. Then mix UMB No. 2 with UMB No. 4 to create Yellow-06. Then mix No. 3 with UMB No. 4 to create No. 7. Next mix Yellow-06 with No. 7 to get No. 13. Finally make more No. 3 and then mix it to No. 13 to make V-Jolt.
An easy way to remember is 1+2=3, 3+4=7, 4+2=6, 6+7=13, 13+3=16 (Water=1.)
