Driving Test mission: Repeated dialogue
On the Con Girls episode, in the normal introduction of mission four "The Driving Test", as Nick enters "The Spot", he walks by one of the goons that vandalizes his brother's dojo. The punk's speech is exactly the same as when he is talking to Nick in the Vandal Wrath mission.

When you are supposed to flee from other cars shooting at you, look for big open spaces like the Staples Center parking lot and drive through them. The people chasing you will stay on the road and go all the way around, giving you a good chance to escape.
To escape easily while in pursuit, drive to the nearest highway. Try to get a good lead from the enemies before you do this. Drive up the branch of the highway, and keep straight. Do not leave the highway. Enemies are not able to get on the highway when you do this. They stick to the main road. Keep straight and eventually you will gain your points and end the mission.
When trying to escape from an enemy in a Rush mission, take out the cars that are chasing you and they will not follow. This takes about thirty seconds.
To escape a chase, find a parking lot or a park and go into the middle of it. Once there, enable the "bullet time" mode and shoot out the tires of your opponents car. For a quick escape, wait until they turn around and shoot their licensee plate to blow them up.
When you start, drive normally until the car chasing you is almost bumper to bumper but next to you. Then, stop as soon as it seems it is past your back wheels. Go into first person view in the car. Aim for the tires and blow them out. When your ''bullet time'' runs out, start aiming at the back of the car or shoot the engine. When the car seems completely on fire, make your getaway.
On a mission where you have to get away from a certain person, turn your car around and start shooting at the person who is chasing you. If you blow them up, they cannot chase you anymore Note: Use precision aim to shoot out their tires. Note: This will not work for all getaway missions.
Blow up cars easily
Drive up behind a car and go into "bullet time". Then, aim at the license plate and fire. Most of the time it will take a single shot. For cargo trucks, aim under the passenger side and slightly to the back and fire. This makes stopping street racers and other people easy.
To explode a car in one hit, go into aim mode and wait until your aiming crosshair appears. Then, shoot when it turns red. If it does not turn red, then just shoot around the license plate until the car explodes.
Stop street racers
While following a speeding car or truck, aim directly beneath the back bumper so that your bullet hits the bottom of the car. Do this repeatedly and the car will explode. Note: Do not do this if you are trying to get a Good Cop rating.
When your enemy is escaping by stealing a getaway car, kick them when they are pulling out the victim to stop them.
Getting enemies to surrender
When you are doing a crime patrol involving people with guns, fire a warning shot and slowly walk up to them. If they are still holding their gun, either walk up to them and wait until they shoot you, or do a neutralized shot.
Drive around impound lot
In the impound lot where you can choose from the four cars you unlock, honk the horn a few times, then go in reverse before you hit the gas and you can around the lot.
When you are on a mission where you need to drive on the world map, do not press any buttons. Nick will start driving like the other cars until you take over.
Bashing through walls
There is a way to bash through the walls that crumble when you attack them. Simply drive at them at a very high speed so that your car drives straight through before the crumbling of the wall is over. This is useful when being chased by gangsters, cops, etc., as they cannot get through.
Flip a car by a bridge and it will fly into the air and give you a score for highest air, etc.
Slide across hoods
To do this, you must be running at a medium speed (if running at full speed, nick will jump over the car). Run until your are right next to the car then press [Jump]. Nick will slide across the hood. This works on any vehicle.
Spotting illegal drugs
To avoid wasting time frisking innocents, look for people that walk differently. Also, when Nick says "hmm", check that person for weapons or drugs.
When an opponent is dazed, you can hit them hard into the wall with a finisher to do even more damage.
Deadly knife throw
In some situations when a enemy drops a knife, you can pick it and throw it. If thrown correctly, it will impale their forehead, killing them.
Learn where the impound garages are located. When you get low on health, just visit the garage. You will not only get a fresh car, your health will be full again.
Easy knock out
When chasing an opponent, shoot them with a weak gun a few times until they are almost dead. Put away your guns and fight when you catch up to them. This makes it easier to defeat an enemy.
Increasing Cop rank
Go around checking everyone for drugs and weapons to get +1 Good Cop.
Go to the Hancock Park area in the middle of the map. On a street corner at 2nd and Citrus Ave., you can frisk just about anyone close to or moving to the intersection and almost always finds drugs or weapons on them.
Go to Ozone Ave. in Venice. Just about every person there will have weapons or drugs.
Go to 4th and Hill. Just about everyone there has drugs or guns.
To increase your Good or Bad Cop rank easily, replay a stealth mission and choose your attack accordingly.
To increase your Good Cop rank, walk on any street near from somebody. If they look at you, it means that they are clean for drugs or weapons. If they do not look, they have illegal things like guns or drugs. Arrest them and you will hear a sound of good cop. Note: Do not try this with people who are talking by a phone.
There is a street where almost all of the people you arrest will either be carrying drugs or weapons. To get there, take Highway 10 east or until you get to where Highway 10 and Highway 405 cross over. It will be near the east side of the map. Take Highway 405 south. When you merge with Highway 405, take the very first road off Highway 405. It will be backwards, but it should lead to National Blvd. When you get off Highway 405, you should turn left. After you pass Sawtelle Blvd., go down until you are about slightly halfway past Sawtelle Blvd. Get out of your car and frisk someone. They should have drugs or weapons.
Play a stealth mission with a lot of people and use only stun attacks, then complete the stage. Wait until the auto save is finished. Then, exit to the main menu and resume the game. Play the stealth mission again. Repeat until you get the desired good cop rank.
In the Hancock Park area on Highland Blvd. between 3rd and 2nd Street, mostly everyone has illegal drugs or weapons. The street is located just above the "O: in Hancock Park on the map.
In Hancock Park on Highland Blvd., between the white picket fence and the green shrubs, most people you stop will have illegal drugs and guns, even those on their cell phones.
On Second Street between Irving Bvld. and Lorraine Blvd., most everyone you stop will have drugs or guns.
Start a fight with a pedestrian, and when you stun them, knock them over with a special move. Before they get up, take out your guns. Once they are standing, they will surrender and you can go in for the arrest. Note: this will not work if the pedestrian is carrying a gun; frisk them before you start fighting.
If you are in Venice, immediately start driving towards the apartments by the ocean (refer to the map). These streets are somewhat small, so they may be easy to miss. Drive around and you will find a street called Dudley. Everybody there is carrying drugs or weapons. Note: Dudley is by Ozone.
Everyone along Ocean View in Venice, at the far southwest on the map, is carrying drugs or weapons. You can go up each street along Ocean View up to one block and everyone there will have something illegal on them. Also, armed muggers do not fight back on those streets. Just draw your gun and they will drop their weapon.
Decreasing Cop rank
Simply start killing people. When you kill about thirty people, the S.W.A.T. team comes after you.
To drive very recklessly, enter a vehicle with hard power (bus, truck etc.). Drive around and crash many cars. When you crash about twenty-five cars, you will soon jump and crash. Get out of your vehicle and shoot it in the back. You will nowhave a reckless driving and killing rating; get many bad cop ratings; or get killed very easily and loose about two shields.
Shoot out both back tires of the selected vehicle and reverse.
To get the S.W.A.T. team on you, kill a number of civilians (about thirty). The S.W.A.T. team will come after you in black vans.
If you are stuck behind a fence that can be broken but do not have a car to break it with, Run at it and press [B]. This will cause you to dive through the fence, breaking it and freeing yourself.
Get past fence
When in a blocked off place with a fence on the other side, go up to it and face it. Do not press any buttons. The game will put you back on the other side within five seconds. It is easier to do this than hit the fence and not get through.
Defeating General Kim
To defeat General Kim on the building rooftop, start the fight by running up to him. Either clothesline or slide kick him. He may block it, but there may a chance to hit him. After this, start kicking or punching him. He will block most of your attacks, but you will eventually throw a successful punch or kick. Then, keep attacking with that same attack until he gets dazed or starts blocking. If he blocks, switch attacks (for example, from punches to kicks or vice versa). Keep attacking and doing the same thing. When he gets dazed, you can either grapple him or do a finishing move. He may start to attack when you start a new combo or may attack you when you switch between attacks; be ready to block when he does this. It is unlikely that he will land a successful attack in the middle of your combo, as you will have struck first. Take advantage of this. If you want to do a finishing move, make sure that you do it near the walls so that it inflicts more damage. When he is on the floor, try stomping on him. You may miss most of the time but you may land a successful stomp in. It is also ideal to have a Good Cop rating when fighting him.
To defeat General Kim on the airport runway, you must have the highest Good Cop rating. After getting this, you can fight in a similar way as you did on the building rooftop. Your goal is to get him as dizzy as possible. When you start the fight, look around the area for an iron pipe. When you find one, try attacking him with it while trying to defend yourself. When he gets dizzy, do the move where Nick swings the pipe over the head. It may do some extra damage, although you may not see the difference. Keep repeating this until the fight is over.
Defeating ancient Wu's concubine
The easiest way to defeat ancient Wu's concubine is to run to the ropes and do a running attack. The rope will break. Go back and fight the concubine. Force them to fight where you broke the ropes and you can hit them off.
Defeating Wu's dragon
When the dragon is about to use his fire attack, use you manual aim to shoot it in the mouth, thus avoiding its fire and tail attacks.
To kill Wu's dragon while he is swimming in lava, switch to manual-aim. Aim for the dragon's eye. This will hurt him.
Defeating zombie during Wu's mission
After beating up the chefs, a zombie will appear. Go near a stove and kick it. Hopefully, you have not destroyed it while fighting the chefs. The stove will explode and both of you will catch fire. The zombie will get greater damage than you. Repeat this with the second stove. If the zombie is still alive, knock him into the fire. Note: It is not possible to kill the zombie with physical attacks.
Damage multiple enemies
When fighting multiple enemies, kicking will damage more then one when you get the chance. Also, you can send enemies flying at other ones. This will damage the one who just got another person thrown at them.
Jetting Away mission: Easy completion
When chasing the plane with Rocky, get behind it and go into "precision targeting". Shoot the engines until they explode, then the whole plane will blow up.
Slaughterhouse mission: Cannibals
While walking around this mission, you will eventually see human bodies on the conveyor belt. If you shoot a body, all extra ice will be blown away.
Spa Infiltration mission: Ten good deeds
Good judo chop (Good Cop) everybody on the level. At the boiler room, go in the middle and chop the man in the chair. Go around the boiler and chop the guard. At the end of the level, go to your right and chop the man in the chair, then go to the left and chop that man, being careful not to hit any buckets. Then, end the level and repeat.
The Staples Center parking lot is the perfect place to drift. It is very big and open.
Get into the airport landing strip
One of the car parks at Airport Ave. has a little gap at the far left side. Go through the gap and you will be in the airport landing strip.
Vigilante 8 reference
During one of the street crimes, the woman in the radio says that a stunt car has been stolen during the shooting of Vigilante 8: The Movie. Vigilante 8 was a game done by Activision for the Nintendo 64 and PlayStation.
In the game, there is a billboard that reads "True Crime: Streets Of L.A.: The Movie, Fall 2005".
Under one of the highway overpasses, you can see your partner's name, Rosa, in graffiti on the wall.
In several parts of the city, there is graffiti on the walls, usually spelling people's "tags". When you find one, start a new game and enter it as a license plate to unlock an alternate character in that game.
There is a billboard similar to the one announcing the 2005 movie. However, this one has a J with a star similar to the logo for Rockstar games. The billboard also says "Jockstrap" in a similar font to that of the Rockstar logo. The picture on the billboard that is of a pink jockstrap.
Some places throughout the game are spoofs of real businesses. For example "OK Price" and "Burger&Fries" are spoofs of "Best Buy" and "Burger King".
National Security reference
When you drive near highways, you will see a white (sometimes black) Ford Crown Victoria (with triangle back-lights). Look closely at the license plate. You will sometimes see the plate reading 2CQN654. This was a license plate from the movie National Security at the ending, when the cop asks for the license plate number.
