Grand Theft Auto IV/Secrets

Grand Theft Auto IV contains several hidden features, cheats, perks and Easter Eggs. This page is an attempt to list them all.

Cell Phone Passwords
To use theses, pull up your cell phone in the game and dial the number. Some cheats will disable certain achievements. To re-enable these, you will need to load a savegame where these cheats were not used to continue gaining achievements. (Calling ZiT and getting song information does not disable achievements.)

Computer Passwords
To enter these, enter them in the URL on an in-game computer. This will not disable Achievements.

Heart of the the Statue of Happiness
If you are legal to go to Happiness Island (steal a helicopter and fly there). Go to the feet of the statue of happiness and jump off; if you land on the top platform, then run to the doors and you see a ladder. Climb the ladder and you will see a beating heart with chains on it. This is the heart of the statue of happiness.

Liberty City Stories Ringtones
When you are selecting ringtones for your cell phone, some of the "modern" ringtones are actually songs from Grand Theft Auto: Liberty City Stories.
