Hint: Taking out key suspects:
To disarm key suspects easier without killing them,
raise your Detective level by solving street crimes to unlock
the Taser pistol and Tranquilizer rifle (found in police station's
basement armory). These work well for safely capturing key suspects
without killing them accidentally, and is much easier than trying
to get an aim on their arms or legs for a "neutralizing shot".



Hint: Inspecting trunks:
To inspect a civilian's car trunk to see if they have
illegal items, stand in front of their car and press Select
to show the driver your badge. The driver will get out and stand
at the side of the door. Get to the back of the car and press
L2. You will open the car's trunk. If the driver has an
illegal item he will start to run. You can shoot the driver in
the arm or leg (when the crosshairs are blue). The driver will
fall and you can arrest him or her.


Hint: Neutralizing criminals:
To neutralize a criminal person that is running, take
out your stun gun and use it until his or her health is gone.
You can then arrest him or her.


Hint: Getting criminals to surrender:
Enemies are more likely to surrender if you fire a
warning shot from a gun larger than theirs. You can then proceed
to arrest them without starting a gunfight. Note: This does not
always work.


Hint: Fighting styles:
If you are having trouble completing a fighting mission
where you must fight thugs hand-to-hand, it is best to drive around
to different Dojos when not on a mission to learn different fighting
styles. Some styles are better used on some opponents than others.
The best styles are Thai Boxing and Tae Kwon Do. They seem to
be effective on a wider variety of opponents and can defeat more
fighting styles than other ones. Also, do not overlook your default
"Brawling" fighting moves as they can prove very effective
against some of the fancier martial arts like Wushu. Switch between
styles while in combat to find the best one for each situation.
If you can score hits with combos of three or more moves on one
opponent without them blocking any of your hits (or stunning them),
then your style is better than theirs. Also, during the "fight
club" mini-missions you can sometimes get a hint as to what
styles your opponents are going to use by the little gestures
and moves they make before the beginning of a match. The best fighting style is the simple "knock down and boot!"
strategy. To do this, purchase the skill from the dojo where you
change your normal radial attack into a roundhouse kick. Then
when you are fighting someone, always attack first with a roundhouse
(X + Square) to knock them on the floor. Then, just
repeatedly kick them while they are on the floor. You also could
grab them up (Circle) and try a grapple on them.


Hint: Fighting strategy:
When fighting hand-to-hand or unarmed against multiple
opponents, do not let yourself get surrounded. Even though you
can block attacks by holding R2, you can still get hit
from behind. Try to single out opponents and focus on one at a
time. Hold R2 to block anytime your not on the offense
and strike immediately after an opponent attacks (and you block).
Block any moves thrown at you, then quickly release R2
and tap X(3) to stun the opponent with three quick strikes.
Then, immediately follow up with three heavy strikes (Square)
to knock them to the ground. This gives you time to run over and
kick them while they are down, or focus your attention on other
opponents. Make sure you learn the Dojo move for the ground attack
so you can knock away opponents around you and get up quickly
if you find yourself kissing the pavement. If you are fighting
opponents that are slower than you or are constantly using heavy
attacks, hold R2 and tap Circle as they attack to
do a counter-grapple move. If you happen to get grabbed by an
opponent or knocked to the ground and they are on top of you,
move the Left Analog-stick back and forth to break free
or do a counter-attack. If your opponents are armed for melee
in any way (with debris, pieces of the environment, or with any
hand-to-hand weapon), immediately back off and look for a weapon.
Chances are you fill find one laying around if your opponents
have one. It is important you match your opponent, otherwise you
cannot block their attacks. If possible, out-do them weapon-wise.
If they have a club, grab a blade. If they have a blade, grab
a blade and a club. Never forget you can fight with more than
one melee weapon.


Hint: Defeating hand to hand combatants:

Another way to defeat some enemies is to grab them,
attack with either X or Square button, then kick
them until they get up. This is done when not in stealth, but
when in hand to hand combat.


Hint: Defeating President Lincoln:
When fighting President Lincoln makes sure that you
have bought the tranquilizer gun at the police armory when you
have reached the second rank. Stand in the room with all the thugs.
Shoot out the window and zoom in on Lincoln across the scaffold.
Shoot him until he passes out. Then, interrogate him.


Hint: Sour Candy mission: Easy completion:

In the Palermo mission "Sour Candy", follow
Candy up the climbing wall to the track. Instead of starting the
race, go in the opposite direction. For the first two sets of
hurdles, break the ones in the center lane by running into them.
Then, break the last two sets of hurdles on the inside lane of
the track. This will allow you to run in the race and not have
to jump. Candy will be forced to jump over the hurdles slowing
her down, so you can catch her more easily.


Hint: Non-fatal shots:
When arresting people without killing them, go into
aim mode by pressing R3. Put your sight over either their
arm or leg, wait for it to turn blue, then shoot. They will fall
to the ground, and you can then arrest them. This is useful for
increasing your Good Cop rank.


Hint: Faster shotgun reloading:
when using a shotgun, slow reloading can be a big problem.
When you start to reload a shotgun and just stand there, it is
very slow. Start running around to reload almost three times as
fast.


Hint: Stun gun precision aim:
The game normally will not let you go into precision
aim mode with the stun gun. However, there a way to do this. Select
the stun gun from your weapons, then press Down to enter
your fighting styles. Press R3 to enter precision aim.
You are now armed with the stun gun in precision mode. You can
fire shot busts of electric charge from it at close range. It
has little effect and is more for amusement purposes. To exit,
press Left, Right or Square.


Hint: Recommended vehicles:
The best vehicles to use at Detective Rank 2 is the
5.4L SC V8 coupe; and at Detective Rank 4 the 6.0L V8 coupe. If
you use the 6.0L coupe, make sure to take it to a garage and get
a street upgrade. Also, if you find one of the bullion vans driving
around, hijack one. These will push any car out of the way, and
in one hit you can sometimes put a car on black smoke. If you
are stuck on the last driving arena mission (one lap around Central
Park), just keep hitting her car in this truck to get her stuck
for an easy win. The only problem with this vehicle is cornering.
Do not be afraid to use this vehicle like a rhino.


Hint: Easy races:
Purchase the Lamborghini and give it the police upgrade.
When you start the race, turn on your sirens. Civilian cars will
scurry to get out of your way. Note: Try to stay in one lane,
otherwise they will swerve back and forth between lanes.


Hint: Fire any weapon in vehicle:
Usually you are only able to fire your .32 auto (the
small default pistol) while in a vehicle and cannot use other
weapons you have while driving. To use any weapon of your choice
in any vehicle, tap L2 to enter or commandeer a vehicle
as usual, but then press Down to switch from hand-to-hand
combat to firearms and quickly press Left or Right
to select any weapon you have in your inventory before Marcus
gets into the car. You can now use the weapon of your choice while
driving around. This is especially useful if you have a high-powered
or automatic weapon with you while chasing down suspects fleeing
in vehicles.


Hint: Get cops to stop shooting you:
Sometimes, when you are in your street clothes and
shoot at someone in front of a cop, the cop will start shooting
at you. To get them to stop, simply turn towards them and press
Select to flash your badge at them. They should then stop
shooting at you.

Hint: Provoke citizens to fight you:
This is a very good way to clean up all precincts quickly,
without getting a Bad Cop rating. Get in a car and ram into another
car that someone is driving. The driver will get out of their
car angry and start provoking you while throwing a big fit. Get
out of your car while they are still throwing a fit and wait until
you see a health bar over their head. You can now beat them down
and arrest them for a quick and easy three Good Cop and three
Career points. You can repeat this until you clean up the area.



Hint: Character upgrades:
As your rank gets better (5 being the worse, and 1
being best), you can buy better upgrades for your character at
the Police Department Armory, such as better zoom for your guns,
or a more slow-mo dive. You can also purchase new guns to use.
The guns will be in the trunk of your police car that you get
from the garage.


Hint: Easy money:
Walk out in front of a car and press Select.
The driver will get out. Walk up to the person and press Select
again. You will write them a ticket and summon them to court.
You will get $10 each time this is done, but also one Bad Cop
point. Go into a store, extort them, then come out. Walk back in and
repeat as many times as desired to get more money.


Hint: Easy ranks:
If you do not mind earning Bad Cop points, use the
following trick to rank up detective levels easily. Go to a place
where there are lots of people, such as Central Park. Frisk as
many people as you can, plant evidence, and arrest them. You will
get one Bad Cop point if you arrest them correctly. Also, you
will get three career points every time you do so. It should only
take about a half hour at the most to rank up a level. Use the following trick to get easy arrests without Bad Cop points.
Go into a car dealership or a dojo and frisk all the customers
inside. All the customers will have something for you to take
as evidence. Arrest them for extra career points. For easy arrests, run and tackle people, then punch them about
three times. Get off them and someone near or that person will
start to fight with you. Knock them out and arrest them.


Hint: Reload stun gun:
Commandeer any police cruiser, open the trunk, and
you can then reload your stun gun. This can be done repeatedly
whenever the gun is low or empty.


Hint: Keeping weapons:
If you get a heavy weapon like a parking meter, when
you try to switch weapons you will drop it. If you want to keep
it, press Select and Marcus will flash his badge. While
he is doing that, press D-pad Up and the weapon will be
in your inventory.


Hint: Reloading:
There are two ways to reload your ammunition. The first
is by accessing the trunk of any car that you own. This also gives
you access to your personal armory. The other way is to get a
police car then access its truck. Using the police car will refill
all your weapons but will not give you access to your personal
armory.


Hint: Melee heads:
Go into any building and draw a weapon to scare the
people out. When they all leave, the door should be left open.
If you watch closely, you will notice people walking by outside
the store. Equip your rotary cannon. When a pedestrian walks by
press R3 and try to shoot them directly in the ear. If
done correctly, their head will be shot off in one piece, roll
into the building, and can be used as a melee weapon. This may
require a few attempts.


Hint: Instant amputees:
To perform this trick, you will need to have the rotary
cannon or two .50 pistols Equip either the rotary cannon or dual-wield
the .50 caliber pistols. Press R3 and aim at any pedestrian.
To remove the head, aim for a headshot, and when the target turns
red fire once. To remove the left or right arm, aim at the desired
shoulder and fire two shots. For the arm to come off you must
hit exactly the center of the shoulder. If you shoot slightly
outside, the leg might come off. To remove either of the legs,
aim at the desired hip and fire two shots. Note: Only one limb
or the head may be removed per pedestrian. Sometimes the head
may come off in one piece or it may splatter into chunks. The
removed limbs cannot be used as melee weapons at all times. If
only one shot is delivered to the shoulder, the pedestrian will
die but no limbs will be removed.


Hint: RPG fun:
Equip the RPG. Turn on Super Cop mode. Enable the "Invincibility"
and "Infinite Ammo" options at the "Debug: menu.
Fill up your Rogue Meter, have the RPG out, and run. The cops
will follow you. The further you run, the more of them will be
behind you. Sometimes they will send S.W.A.T. teams after you.
Just dodge them. If you want to kill them quickly and easily,
equip your rotary cannon and press R3 as soon as you hear
them radio out the S.W.A.T. When you see them, shoot until you
see a big puff of black smoke above the hood. Do the same thing
with the blue escorting cruiser. Sometimes they will escape. Continue
running as long as desired, then equip your RPG, and without turning
around, immediately press R3. Then turn, aim at the cluster
of cops, and fire away. You should hear a few last cries and see
about twenty to forty small "+20 BAD" messages above
your badge on the screen. Repeat as many times as desired. When
done, , press Select to flash your badge or fire a warning
shot and clear your Rogue Meter.


Hint: Reducing crime rates:
If you are trying to reduce precinct crime rates, go
into a pharmacy. When you get inside, frisk everybody there. The
following are the predicted amounts of people holding contraband.

High crime rate: Approximately everybody.
Medium crime rate: Approximately 50% of the people.
Low crime rate: Approximately two to five people.

Start at the back of the pharmacy. Work your way to the front
of the pharmacy by arresting people with contraband. If the person
is clean, walk them to the front of the pharmacy and release them
there. Hide behind the back shelves when you arrest him or her
so that no one else will see you. Do this so that nobody with
contraband runs out of the place.


Hint: Lower Rogue meter:
To allow your rogue meter to cool down, just enter
any subway station. Cops will not follow you down and you will
be safe.


Hint: Kill without filling the Rouge meter:

Kill a group of people to fill your Rogue meter. Once
the cops come after you, let them kill you. After you are put
you on street patrol, leave the station. Enable the "Super
Cop" code, and you can now kill as much as you desired without
your Rogue meter filing.


Hint: Blow up cars:
Press R3 and point at the back of a car near
the license plate until it turns red. Shoot and it will blow up.
Note: You may get 10 Bad Cop points. This will not work trucks,
buses, fire trucks or anything similar.


Hint: No motorcycle wrecks:
Pop a wheelie and do not stop. Cars will not make you
fall off or slow down much.


Hint: Keep car door open after you jump
out:
When you jump out you will find that your door is stuck.
To keep it open, get in on the passenger side.


Hint: Redman Gone Wild mini-game: More
time:
An easy way to get more time is to kill people. It
is impossible to complete it by just driving. You must get out
and shoot them.

Hint: Grand Theft Auto
reference:
When you get the option to start driving taxi missions,
Marcus comments that he cannot believe it and says "Next
thing, I'll be flying remote control toys and shit." This
is obviously a reference to all the RC car/plane/helicopter levels
in the Grand Theft Auto series of games.


Hint: Puff Daddy and Jennifer Lopez reference:

One of your crime calls on your police radio will be
a reference to the Puff Daddy and Jennifer Lopez incident in Club
New York, a midtown Manhattan nightclub on December 27, 1999.
"Puff Doggy (Puff Daddy) and Jo Loleta (J.Lo, Jennifer Lopez)
have seen escaping the scene in SUV, apprehend suspects."



Glitch: Wrong subway map:
When you go into the subway, walk from the stairs down
to the other end of the platform. There will be a wall, and on
the wall is a subway map. However, if you look close, you can
see that this is not the NYC subway map; it is actually the map
of the Boston, MA public transit system, the MBTA. The words are
not there, but the shape of the lines, and the colors are 100%
accurate to Boston.

Glitch: Hear turbo boost sound effect when
not in car:
If you have acquired the rank 1 driving skill, Turbo
Boost. you can hear the sound effect when you are not in a car.
To do this, steal or get one of your own cars and press X(3)
to activate the boost. Then, quickly exit the car. You will continue
to hear the sound effect. To stop this, either get back in the
car and do another turbo boost and let it finish, or blow up the
car.


Glitch: Swim in air:
Go into any subway. Wait until the subway train arrives,
and when it is slightly past you, run into it until the screen
turns gray then release the Analog-stick. After a while,
Marcus will appear in the middle of the screen swimming. If you
move the Analog-stick, he will die and you can repeat the
glitch.


Glitch: High freefall:
Enter the "Debug" menu. Note: If you do not
want to die afterward, turn on the debug combat option. You should
initially have a highlighted "missing text" and "normal"
message. Press R3 once to change to "debug",
then press Start. Notice that time in the game has frozen.
You can move the camera, but not Marcus. Note: This is also useful
during a chase if you cannot get a car. Aim the camera upward,
hold the Left Analog-stick Forward, and hold R1.
Notice that this speeds up movement of the camera. Keep holding
that position as long as desired. Eventually past the clouds,
sun, and stars you will appear in a light blue area, still moving
upward. Press Triangle to bring Marcus to your current
location. Go back into the debug menu and change the "missing
text" to normal again. Press Start, and Marcus will
begin a freefall from the blue area, through the sun, the clouds,
and he will eventually hit the ground. Note: Do not try to move
while using this trick while in a car or the game will freeze.
Also, do not move an extremely long distance from current location
or through buildings to avoid freezing the game.


Glitch: Turn Marcus invisible:
Buy a .50 sniper rifle. Go to the driver's side of
any car and press R3 then L2. Marcus is now invisible.
Get out of the car and Marcus will re-appear in four or five seconds.




Glitch: Gory Marcus:
Enable the "Zombie mode" code once or twice.
Run around, drive, dive-tackle pedestrians, and swing melee weapons.
Eventually Marcus' head and limbs will reappear, and there will
be a bloody meat chunk around his lower jaw. You will be able
to see the bones in his knees and elbows, and they will still
be spurting blood.
