Hint: Defeating the Madness Mansion Boss
in the well:
Sometimes the creature will come out further from the
well, exposing an eye in its belly. Shoot this to cause massive
damage to the creature.


Hint: Tattoo on woman from Chemical Plant:

Start any type of match in two player mode. Have person
play as the woman from the Chemical Plant mission. The other person
can be character. Walk up behind the woman and look at her shoulder
to see a rose shaped tattoo on her shoulder.


Hint: Scifi Autorifle Grenade:
Start any normal game and get a Scifi Autorifle. Press
R1 to launch a grenade into your target. This attack will
cost ten Scifi shells.


Hint: Triple rockets rocket launcher:
Select any kind of game (story or arcade) and choose
either select the rocket launcher as a weapon or find it in arcade
mode. Once it is in your possession, press R1. This will
fire three or more rockets at one time. Note: This will take three
shells from your rocket launcher.


Hint: Character differences:
Some characters can endure more damage than others.
For example, Siamese Cyborg and Insect Mutant. Others are physically
stronger. For example, Tuxedo Cyborg and Zombies. Fast characters
include Badass Cyborg and Float Alien, who can run very quickly.



Glitch: See inside person:
Start any type of match in two player mode. Kill the
other player and make sure that they do not press X. Stand
exactly above the dead body to see inside the person.


Glitch: Easy points:
Make a industrial-type map and only put the largest
room in it. Customize it so that the only guns are up at the very
top right corner of the room (the small sniping stop). Save it
and go into the game with a friend. Customize the weapons and
only put in the sniping rifles and one other gun such as the autorifle.
Put as many bots in as possible. After the game starts, get the
guns from the small room. Go outside that small sniping point
and to the right. Slightly below the door is something that appears
to be a vent. Back up, run towards it, fall off the ledge, and
into the vent. You should now be outside of the game. Walk all
the way around to the other side and just stand there, waiting
for the people to appear. The glitch cuts the map from your view
in half, but you can still shoot anywhere. However, you will not
be able to see what you are shooting. At the small doorway that
you were at, a wad of bots will begin to group and try to snipe
you. If you have them set at one star, they will never kill you
due to their poor accuracy. Have your friend help clear that doorway
and the bots will just keep reappearing. You will look as though
you are in the game and can be shot -- back up and you will leave
the room and will not be seen at all times at some views. This
is a great way to improve sniping skills and get a lot of head
shots.


Glitch: Sitting ducks:
Play an arcade level with the weapon set to custom
1 (no weapons selected) and have "Start with weapon"
enabled. When you start the level, the CPU players will not move
and will be sitting ducks for you. This is a perfect chance to
achieve 100% accuracy and head shots.


Glitch: Headless allies:
Play a regular arcade game of Capture The Bag or Deathmatch
and turn "Friendly Fire Damage" off. Set the players
you want on your team to be either zombies or mutants. When game
play begins, find one of your teammates and shoot at their head.
It should go flying, but they should still be able to move around
and shoot, because you cannot damage them. Note: Your allies must
be controlled by the CPU.


Glitch: Chinese: Paintball marks on reflection:

Go underneath the bridge in paintball mode on the Chinese
level. You will see a reflection of the bridge. Shoot the bridge
in the reflection. Marks will appear on the reflection.


Glitch: Mansion: Headless zombie:
When you play the Mansion level under challenge mode,
shoot a zombie anywhere but the head. When they fall on the ground,
get ready for a head shot. When he puts his hands on the ground
and starts getting up, shoot him in the head. If done correctly,
the zombie should get up without a head. Shoot him anywhere else
on the body and he will die.


Glitch: Streets Deathmatch: Opponent acts
if hit:
Select arcade mode, Streets, and Deathmatch. Put the
MI6 x2 on, use all the ammunition for the MI6 x2 until you run
out. Keep firing and aim at someone. They will bend over and act
as if they got hit while firing.


Glitch: Mine in water:
Find a toilet and shoot the water. It will not splash,
but instead will make a hole. Leave a remote mine in the water
and it will stay there.


Glitch: Floating mine:
Stick a mine on glass. Break the glass and the mine
will remain floating in air.


Glitch: Drifting gun:
Select any character that holds a gun in arcade mode.
Wait for about five minutes and the gun will slowly drift away
from that person's hand.



Glitch: Chastity's levitating gun:
In deathmatch mode, select Chastity Detroit at the
character select screen. From this point on, do not press any
buttons and let the animation where she folds her arms complete.
After a few minutes, her gun will slowly begin to separate more
and more from her body, until finally it appears that she is levitating
it.
