Cheat Codes

Resident Evil 5

Easy Final Uroburos boss:
-------------------------


To make the final uroburos boss easier, upgrade the Lightning Hawk all the way
and purchase unlimited ammo for it (15,000 point) fight the uroburos and this
will be easier than fighting it with the LTD.


Inventory Duplication:
----------------------
This requires two very cooperative human players, and a Live connection (or a
split screen game and two profiles).

1.In the Inventory Lobby, invite a friend.
2.Start the level (use 1.2 to make it easy). Have the host hand items (Rotten
  Eggs, First Aid, Ammo) off to the guest for duplication.
3.With a full inventory, have the guest leave the game (it should say "All unsaved
  progress will be lost" -- select "Yes").
5.After selecting "Yes," another question for the guest will appear asking whether
  or not to save status and ammo. Choose "Yes" to save and you will have all the
  passed-on inventory saved.
6.Now, back to the host: Quit out of the game, but at the second question, choose
  "No" and do not save ammo and status.
7.Restart the game with the two characters and you'll both have the ammo and items.
  Duplication successful! (Note: You cannot do this with weapons as you cannot hand
  them off to your partner.)
Addendum: A popular money-making strategy involves duplicating Gold or Rotten Eggs.
These are worth $2,000 a pop, and 5 can be crammed in each inventory slot. That means
you can eventually be duplicating $90,000 each time. Finding Rotten Eggs can be tough;
they drop randomly from enemies in later levels. Also, for two people to increase the
amount of eggs quickly, you'll have to pass them back and forth, alternating who is
saving and who isn't. Finally, you may request eggs from the computer once the guest
has quit out to make this process faster.


Unlimited Ammo:
---------------
To unlock unlimited ammunition for a weapon, fully upgrade all of its attributes,
complete the game (all chapters) and buy the ability using Exchange Points from
Bonus Features (for that weapon only).


Discarding Weapons in Mercenaries Mode:
---------------------------------------
In Mercenaries mode, ammunition drops are based on the type of weapons you have.
Use this to your advantage by discarding weapons you don't use. This causes more
ammunition to be dropped for other weapons. Example: For Wesker (Stars), drop the
Samurai Edge to find more Magnum and Shotgun ammo.


Unlimited Ammo for All:
-----------------------
Once you unlock unlimited ammo for a gun, it will be unlocked for all copies of that
gun you may have. Buy one for your partner so they can join in the fun! Note: You'll
still have to fully upgrade any additional weapons to get their maximum power.


The Heart of Africa:
--------------------
There is a special treasure to be had in the boss fight with Jill and Wesker. If
you beat up Wesker enough in the seven minutes he has to spare, the Heart of Africa
treasure will appear between the two stairs on the bottom level -- behind where Jill
spawns during the second half of the fight (and you can pick it up in the second half
too). One Rocket in Wesker's well-groomed face will do the trick (you have to shoot
the rocket with another rocket or a gun while he holds it). Hide at the end of a long
passage after he kicks you through the wall. Soon you'll see on your map that he's
spinning around, looking for you. Shoot him with a rocket then.


BSAA Emblems:
-------------
Below is a list of how many BSAA Emblems can be found on any given chapter in the
game. There are thirty emblems total, and not each chapter has one.

Chapter 1-1 - 0 Emblems
Chapter 1-2 - 3 Emblems
Chapter 2-1 - 5 Emblems
Chapter 2-2 - 3 Emblems
Chapter 2-3 - 0 Emblems
Chapter 3-1 - 4 Emblems
Chapter 3-2 - 2 Emblems
Chapter 3-3 - 1 Emblem
Chapter 4-1 - 3 Emblems
Chapter 4-2 - 1 Emblem
Chapter 5-1 - 1 Emblem
Chapter 5-2 - 1 Emblem
Chapter 5-3 - 3 Emblems
Chapter 6-1 - 3 Emblems
Chapter 6-2 - 0 Emblems
Chapter 6-3 - 0 Emblems


Hidden Dialog:
--------------
If you wait around long enough at the very beginning of Chapter 1-1, before any
checkpoints, you will trigger a conversation between Sheva and Chris in which Chris
gives a scathing critique of the American Dream.


Hidden Cutscene:
----------------
At the very start of Chapter 1-1, take your first right just past the building and
you'll see a quick cutscene of a fellow in an unfortunate predicament.


Easter Egg: The Chair:
----------------------
In this immensely stupid Easter Egg, Chris and Sheva can take a short rest in a chair.
There are chairs in Chapter 5-3 (at the beginning of the chapter, far end of the lab)
and Chapter 6-2 (the Captain's seat). That is all.


Wesker's Dash Attack:
---------------------
When using the unlockable character Wesker in Mercenaries, you can click the Right
Analog Stick (sometimes called R3) to initiate a dash. Press both Triggers while
dashing to do a knee attack. Warning: This move will drain your own life meter, so
use it sparingly!


Giant Crab Tips:
----------------
When you are fighting the giant crab in chapter 5 then you probably know you have
to shoot at the red tips on each leg, but when the monster comes crashing down and
opens its mouth, shooting at it does absolutely nothing. What you are meant to do
is get hand grenades (if you have none then look around the circle computer and you
will find 2 herbs (green) and a hand grenade, DO NOT throw it at the beast. It also
does nothing, go near the mouth when it is open after you have shot at the legs then
it will say "press 'X' to throw" obviously you should press 'X' then Chris will throw
the grenade in its mouth and the top shell will fall off. You must do this twice. If
you have no grenades, bad luck you have to wait for the mosquito-like things (i call
them Skeeters) and shoot them and they will drop a grenade sooner or later, then after
you have done that twice, RUN! he will swipe without warning and it will be a one hit
kill, no "dodge" chances at all, just run. When you have done all that, the easy part
is getting your handgun (by the way the mosquitoes drop X20 bullets at a time, a good
idea to pick em all up.) and shooting it once in the brain, it will be dead after
that.


Train Station: Hidden Majini:
-----------------------------
In the third part of the level, find the green portable toilet past the truck with
a Gatling gun. Knock on it to find a hidden Majini.


Completion bonuses:
-------------------
Successfully complete the game under any difficulty setting to unlock the following
bonuses.

* Chris' Safari and Sheva's Clubbin' alternate costumes
* "History Of Resident Evil" option
* "Infinity ammunition" option (must fully upgrade a weapon then purchase the unlimited
  ammo from the "Bonus Features" section with points)
* Mercenaries mode
* New Game+ mode
* Play as Sheva Alomar
* Successfully complete the game under five hours (get an "S" rank) under any difficulty
  setting to unlock the Infinity Rocket Launcher.
* Successfully complete the game under the Amateur difficulty setting to unlock the
  "Classic Horror Filter" option.
* Successfully complete the game under the Normal difficulty setting to unlock the
  "Retro Filter" option.


Easy money:
-----------
* This trick will help you gain money to max out and buy all the weapons. In any chapter,
collect as much gold, items, ammunition, and treasure you can find. When you are satisfied,
pause game play and quit the game. Save the game when prompted. Restart any desired chapter.
The "Shop" menu will appear before the start of any chapter. Notice that all the gold,
treasure, weapons, and ammunition from your previous saved game are still in your inventory.
From there, you can sell anything you want to gain some fast cash. This glitch can be done
repeatedly, on any chapter.

* Go through a chapter, collecting as many hand grenades as possible. Then, start Co-op
mode with a friend, system link, or over the Internet. Give your partner all of your grenades
and have them exit the game. After they leave, your AI partner will still have all of the
grenades. Make sure you request them back. While you do this, your friend that left can sell
the ones he took with him. You can have up to five in each slot, and they sell for 250 gold
each. You will gain 11,322 gold each time you do this (if you have all your slots full).
This is also a good way to stock up on ammunition.

* As soon as you defeat the Uruoburos for the second time you can repeat the beginning of
that chapter and collect lots of money and ammunition (especially for the machine gun).
Repeat this several times and you will be able to upgrade every weapon in your arsenal.

* Once you have completed the game, go to Chapter 5-1 (Underground Garden). Bring extra
ammunition if possible. Follow the chapter until you have reached the part with all the
Lickers. Do not press the button to the elevator yet. Kill all the Lickers that are there,
then gather all the treasures and money they dropped. Press the button to the elevator.
When you do this, about four or five more Lickers will appear. Also kill them. Once again,
gather the treasures. Then, quit the game and repeat until satisfied. You should make about
10,000 gold selling the treasures the Lickers drop. There are no enemies except for the
Lickers you are meant to defeat, which will make for easy money for weapon upgrades.


Easy quick game:
----------------
Use the following trick to get a combined clear time for the entire game of under five
hours (to unlock unlimited RPG ammunition). A really easy way of doing this is to play
under the Amateur difficulty setting and just run pass all enemies. Only kill story-driven
enemies (ones that hold key cards or those that must be defeated to advance the game). Also,
avoid any crates, barrels, or treasures. Attempting this with a friend instead of the CPU-
controlled Sheva is recommended. Note: You do not need to purchase the infinite ammo in
"Bonus Features" as you would do for normal guns.


Quick reload:
-------------
Display the inventory screen and combine ammunition manually with your weapon. This causes
weapons such as the shotgun to reload much faster than the normal method. You can also use
this trick while climbing ladders or jumping. Reload your weapon when the melee option appears.
Then, start the melee sequence. Your weapon will be reloaded instantly.


Dodging:
--------
Picking up an item allows you to dodge an attack. This works best when surrounded by enemies.
Stand above an item on the floor while shooting. If you miss someone who runs up to you,
just pick up the item. Your character will duck the attack and the enemy will be open for
a counter-attack. Kill him, stand over the item that he drops, and continue.


Efficient healing:
------------------
If both players stand in front each other and one of them heals themselves, both persons
will get healed.


(Desperte Escape) Unlockable: Figures:
--------------------------------------
Beat the game to unlock figurines you can view in the bonus galleries.


Devil May Cry 2 reference:
--------------------------
The name for the virus in Resident Evil 5, Uroboros, is also used as a name for the
corporation in Devil May Cry 2, another Capcom game.


Defeating Q-1:
--------------
When you are fighting the Q-1, get the grenade launcher with acid rounds then shoot it in
his mouth. Throw something in his mouth. Repeat this and it will be defeated in five minutes.


Defeating U-8:
--------------
When you start the U-8 fight, you will need a rocket launcher. When you start, aim at the
U-8's mouth and blast it. It will be dead in less than three seconds.

Easily defeating uroboros aheri and wesker:
-------------------------------------------


uroboros aheri ( transformed exceella) is a pain in the ass , especially if you want to
beat the game in veteran mood. Here's a hint to easyly defeat her. at first, use the
satellite laser guidence weapon to tear tentacles; a giant mushroom type thing emerges
then. all you need is a rocket launcher. fire away and she is done. so remember to buy
a rocket launcher before entering chapter 6-2.

wesker first appears at the end of chapter 5-3 with jill. you cant harm him this time.
all you have to do is avoid him for 7 minutes. thats all.

after defeting excella buy 3 rocket launcher. you can also use that is in the display
case but i found it slow to load. turn off the lights and sneak past wesker. make sure
he doesn't see you. fire one rocket. he will catch it and try to pull it out, fire the
second rocket quickly and he is stunned. quickly go near him and give him the shot.

at volcano quickly run away from wesker and wait behind the rocks in the arena. you
will able to see his back. there is a slimy growth you can see. aim the final rocket
you have and he is done once and for all.
