Grand Theft Auto IV Hints

If the vehicle you are driving breaks down and the engine will not start, call any number from your phone book, and your engine should start again.

Go to an ATM, then cause a traffic jam to the area. Wait for someone to take money from the ATM, then kill him or her. Make sure to block any nearby roads so the ambulance cannot get to the murdered victim. Take the money they dropped on the ground. Then, run a short distance away, and go back. The money should have respawned on the ground. You can repeat this as many times as desired. You can also kill more people taking their money from the ATM to increase the amount of money that respawns.

Get Claude's outfit:
If you choose the kill Playboy X you will take over his safehouse. If you change clothes in that safehouse you can choose to wear the outfit Claude (the main character in GTA III) was wearing. Black jacket, green pants and black/white shoes.

Hidden Shirt:
Get to Happiness Island. Run up to the base of the statue to find a shirt on the ground. Walk over it to put it on. It has a picture of the statue and the text Happiness is... on the front and the text ...land on the back.

The heart of the Statue:
Get a helicopter and fly to Happiness Island. Jump out of the helicopter at the top of the statue's base so you'll land by it's feet. You can not take the stairs this high. Look at the sign next to the door. It says No Hidden Content Here. Enter the door and climb the ladder inside the statue. You will find a big, red, beating heart held in place by chains.

Purple Dildo:
Head inside the old, abandoned Casino where the last mission takes place, at the north end of Alderney. Look at one of the trash piles on the ground to find a purple dildo sticking out.

GTA Graffitti:
Across the road from Bank of Liberty you can find a house covered in graffitti. Some of the artwork is from old GTA titles.

GTA portraits:
Across the street from the museum in Algonquin you can find a portrait painter. The portraits are of old GTA characters.

Old GTA character's names graffitti:
Go inside one of the pink houses near Manny's community center. Go to the back of the inside and look at the wall. You will find graffitti with names from a lot of old GTA characters, like Claude, Tommy, Toni, etc.

OG Loc CD:
In your Bohan safehouse you can find a CD by OG Loc from San Andreas on the floor.

Golf Course Land Marks:
At the mini-golf course at Firefly Island you can find a small version of the giant chicken from San Andreas, the lighthouse from the GTA III version of Liberty City, the Watts Towers from Los Santos and the Ocean View Hotel from GTA: Vice City.

This is how to find children in GTA IV

go to your map, the children are in the bottom left corner of the middle city, near the docks...

they will be there from 22:00-22:15

1) go to the strip club , and wait for a girl to ask you : do you want me 2 dance for you ...
then follow her. let her do 2 dance's. the third dance she will call in a friend of her's ;-)
2)if you steal a car with people in it , then the driver should normaly pull you out ...
if he/she comes back , then just when he opens the door u gotta ride away
sometimes they will keep hanging at the car xD (normaly , but not always , also u need good timing)
3)get a helicopter. fly to hapiness island (liberty islang : with the statue ...)
get to the highest floor where there are still doors (under the feet of the statue)
JUMP OUT! (on the floor where i told you!) there are 4 doors
get into the one with the plaques : "no hidden content this way". climb up
there is THE HART of Liberty City!

At the place where you can ride your motor-bike inbetween the 2 bridges start from the end opposit from the stairs that lead to the tunnel.(u have to be on a motor-bike) go as fast as u can adown inbetween the bridges avoiding thelights and the ppl(u need to be as fast as possible) because if u hit somthing even a tiny rock that has any effect on ur speed, it wont work, so u must restart.then, just before u touch the stairs that leqad into the tunnel slightly lift ur front wheel. so u head is about to hit the wall and nothing else but ur head hits the wall. then when ur head hits the wall u must have died because if u dont die when u hit the wall ur head wont come off. but if u do die u will see there is nothing above ur shoulders and ur head is nowhere to be found.

First, you'll have to have access to Happiness Island. Once you're able to go there legally, find the Helicopter Tours (which is directly east of Happiness Island) and steal a helicopter. Fly to Happiness Island and 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.
