The Heart of Liberty City
Go to the Happiness island (when it is unlocked) and steal a helicopter. Fly over the Statue of Liberty, then jump out of the helicopter at the statue's feet. You should land on the topmost tier of the statue, which is basically a square platform with a door in the center of each side. Run around the platform until you see a door with a plaque on either side of it that reads, "No Hidden Content Here." It may seem like you cannot go through the door, but you can-- it doesn't open, you simply walk THROUGH the door. Inside, you'll find an empty room with a tall ladder. Climb it, and when you reach the top, look up; there is a gigantic beating heart, held in place by chains.
Go to the statue of liberty and walk up to the second level. Walk through the door (it doesn't swing open, just go through it) and the game will load for a second and you will walk out with a new t-shit with the statue of liberty on it.
Repairing the engine
If the vehicle you are driving breaks down and the engine will not start, call 911, and your engine should start again.

Swim through objects
When swimming into certain objects at certain places you can go through them.
Anime Scifi Central
Position Packie between the camera and Niko. Move until the camera is inside Packie and look at the center of his head to find a box with skulls.
Endless armored cars
There is a glitch in Aldeney at the intersection of Tudor and Port Tudor, close to the prison where you visit Gerald. You can find a total of nine armored trucks arriving back to back. Highjack one and then block the road. Another one will appear. Blow them up one by one. There is a total of about $1,100 on each truck, which is useful when just starting out and if you need money.
Get killed or somehow otherwise get to Schottler Medical Center. Enable the "Spawn Sanchez" code. Look at the inside of the hospital from the bottom of the stairs. Keep pressing A on the "Cheat" option of your cellphone until you see a Sanchez appear inside the hospital. Go up to it and get on the bike. Either all the walls will disappear, all the walls will have inverse colors, or everything will turn very bright white. No matter what, Niko will be invisible and so will your gun if you choose to fire it. The muzzle flash appears but the gun itself does not. You can get on and off the bike. Note: If you try to go outside the hospital you will become visible again.
Swim under city
Go to the north part of the map, just northwest of Butterfly Street in Bohan. Once there, get down to the outskirts of the land and walk towards the corner between the brick wall and the cliff. You can walk through the invisible wall. Lookup towards the city to see the city from below. You can also continue onwards and swim under the city.
Weapons: Desert Eagle
To get the Desert Eagle before you can buy it, kill the gun salesman in Broker that has it equipped and take it from him.
Weapons: M-4 assault rifle
Go to the Easton area on Algonquin. At the Grand Easton Terminal, go up the stairs in front. Keep going around that floor until you see a small pond. Move past it until you see a turn going left. Go to the left to get in between a tall building and a smaller one. At the end of the passageway is a dead end. Turn and you will see a glowing orange garbage can. Behind it is an M-4 assault rifle.
You can get the good shotgun early in the game by simply going to the strip club. On the way out, there is a manager's office that you can enter. There is a large Remington shotgun on the floor you can take.
Weapons: Get full pistol and shotgun early
The following is an easy way to start the game with full pistol and shotgun ammo. Unlock the ability to save by sleeping on the bed in Roman's home. Getting the knife is also helpful. Go outside Roman's home and kill a few people. The police will appear. Kill a police officer. He will drop his gun. Take it then immediately run into Roman's home and sleep on the bed. You can choose to save the game if desired. When you wake up, your wanted level will be down, and you will still have the pistol. Go back outside and kill more pedestrians. When the cops appear, run up the stairs. Turn around at the top of the stairs and face the door going outside of Roman's home. The cops will come through that door and you can just pick them off with your new pistol. Watch your health and do not worry about picking up the guns. If your health gets low you can sleep on the bed. Wake up, and when you go outside there will be lots of weapons. The shotgun will take longer because not every cop uses it. However if you enter the police cars that have been abandoned outside the apartments you can easily get five shells for the shotgun for each different car you enter.
