Assaulting warehouses  -  Before going on a warehouse assault have these items: pistol (full ammunition), Tommy gun (full ammunition), shotgun (full ammunition), magnum (full ammunition), molotovs (6), and about $25,000. When going to a warehouse, try to blow up the roadblocks. After that, stand there and shoot at oncoming gangsters with your pistol (headshots are essential). Then, go in to the warehouse area. Stand behind boxes and shoot the enemies with the pistol or magnum (again with headshots). Once you enter the warehouse, have either your shotgun or Tommy gun ready. Most enemies will have shotguns and Tommy guns. When you kill them, search for the owner. He will have puppeteer hands. Buy him out. Do not hit or injure him or you will not be able to buy him out and will have to use pressure. More than likely you will have also started a mob war. Do not bother looking for bombing business. Instead, check the map for the nearest FBI agent and bribe him. You may lose $3,000, but it is less risky. You will now have a warehouse and won a mob war at the same time.

Infinite money and Respect  -  Successfully complete the first mission, then save the game and quit before answering the phone downstairs. Reload your saved game to get $500 and 500 Respect points again from the previous mission. Save the game, quit, then reload again as many times as desired to get $500 and 500 Respect points each time.

Infinite ammunition and $1 million  -  Reach the "Don Of New York City" rank at a 91.5% game completion to get unlimited ammunition and one million dollars. To become the Don, you must take over all businesses and rackets, then complete the contracts on the other families top Bosses.

Extra money  -  Enter the sewer system and find a crate containing money, which is guarded by a group of heavily armed bell-boys. The entrance to the sewer system is directly south of the westernmost Tattaglia warehouse on the Hell's Kitchen Loop.

Extorting businesses  -  If you are having trouble extorting business owners, try destroying some of their property and/or hold a gun to their face. For example, when you are trying to take over Good Eats in Brooklyn, you can hold a gun to the man's face then reholster the gun and extort. If he refuses, simply draw your gun again, lock on, and hold it. Keep doing this until he caves in. Do not forget to reholster your gun to avoid accidentally shooting him. In another example, when you are trying to extort money from the hotel owner in Brooklyn, hold a gun to him twice, break the downstairs cupboard, then finally blow his safe before you beat him into submission. Always buy available rackets first. Take a trip around to either buy another racket or go around the block. Do not attack until you visit again, and instead of enemy soldiers you will find all your soldiers. By doing this you do not have to fight a bunch of enemies and get your vendetta up.

Robbing banks  -  Depending on the type of bank will determine the easiest way it can be robbed. The type with the three guards and one room is by far the easiest, and should be robbed as often as possible. Use the following trick to rob it without being chased or even getting past two shields. First, bribe the cop outside. Then, go into the bank and choke the first guard by the door. Next, go into the vault area and start strangling the guard on the left. The other guard will come and attack you, but he will not shoot. He will only hit you with his billy club. Remember to strangle the man on the left first because he tends to start shooting with his shotgun if you attack the other guard. If you are robbing the big bank, start the same way by bribing the cop outside. Then, go in and immediately strangle the guards in the main room. Hurry down to the vault and strangle the two guards there. Open the door and blow the vault. Three or four guards will attack you as you flee the vault. Get close to them and shoot them with your Tommy gun to perform an instant execution. After you shoot them, run up the stairs and move to the right. Then, take an immediate right to leave the building where the car is always parked. Get in the car quickly because you will be shot at when outside. Take off and you should not be chased once you hit the streets. After any bank robbery you must go to your hangout to get the money. The best bank to rob is the midtown bank, close to the apartment that the Corleone's give you after you save Michael. You wll get $50,000 there.

Taking over compounds  -  To take over a compound, equip all of your guns with ammunition, or use a powerful gun to kill other gangsters and take their gun. You should have cover at all times. Note: When behind the bushes to the left of the entrance they can shoot you through the bushes. Once inside, do the same thing and always have cover. Then, run downstairs. In the back house there are two men. One is behind a box and there is another behind a pillar. After those two are dead, set the time bomb (not dynamite). If needed, stay in the basement and die, then drive back and repeat on the other house.

When you are ready to take over a compound, the Tattaglias in northeast Brooklyn is recommended because they may be the weakest family in New York, but that does not mean they are going to be very simple to defeat either. Bring some bombs along and blow up the support pillars in the basements. You may start a mob war, but if you are successful you will have a new safe house with a group of guards.

Getting past barricades easily  -  When you go to a hub, warehouse, or compound with people and cars blocking your way, get a truck and run into the cars and people until it catches on fire. Then, finish off the other people that are still alive.

No heat for entering parked cars  -  Once you reach the rank of Underboss, you will not get any heat when you enter parked cars.

Easier driving  -  While driving, honk your horn constantly by pressing L3 to send other cars to the side of the road. Additionally, go to a police station and bribe the police chief. You can then steal the police car without any trouble. Press L3 to turn on the siren. Cars will now move out of your way.

Hidden money in "Death To The Traitor" mission  -  After placing the bomb in the upstairs of the bar, an enemy will suddenly open up the previously locked door at the top of the stairs. Quickly run into the hallway to find a massive stash of money bags. Do this quickly by sprinting, as you will not have much time to run downstairs and leave before the bomb explodes. Do not bother trying to open the second door in the hallway, because it is locked.

"The Don Is Dead" mission  -  Before starting this mission, break the windows in the barber shop. This will allow for easy shooting once the Don is shot. The recommended gun for this and any other close range shooting mission is the magnum.

Marlon Brando's last appearance  -  Play the mission when you go to the hospital to protect the Don. After you kill the first assassin and Michael Corleone tells you to go to the basement, go foward and make a left. You should see a door with Michael Corleone talking to Vito Corleone while he is in the hospital bed. Listen to the conversation carefully. This is the real Marlon Brando talking, recorded while he was hospitalized.

Movie and television references  -  There is a man with red hair, a mustache, and a fedora hat who is named Edward Rooney (from Ferris Buellers Day Off) in Little Italy. There is a man with black-gray hair named Mike Brady (from The Brady Bunch) in Midtown. There is a blonde woman walking around in a black dress named Pamela Anderson in Midtown.

Recommended weapons  -  Do not waste money on safe houses. You can make it just fine with the ones you get in the story. Instead, use your money for clothing and weapons. All the best weapons cost a lot but are well worth it. The Saturday Night Special is a better revolver and costs $75,000. The Assassin's Pistol is better gun and costs about $200,000. The Python is a better magnum and costs $250,000. The Dillinger is a machine gun and costs $450,000. Finally, the Street Sweeper, which works like a shotgun, costs $500,000 and will kill most people in one shot.
