Secrets in GTA IV

The following is a list of secrets, Easter eggs, and hidden trivia references in Grand Theft Auto IV.

Easter Eggs

• Inside the Statue of Happiness is a giant beating heart. This is supposedly the "Heart of Liberty City."
• Whilst on a mission with Packie, if you position the camera properly you can look inside his head - inside there is a box with a picture of a brain on it.
• While driving the Mr. Tasty, you can trigger songs to play by clicking the horn. One of these songs is the song from the opening credits of GTA4. While this song is playing, call ZiT and they will text you back with "GTA4 theme song found". This is a cheat that gives the player health, armor and ammo, but also disables some achievements.
• If you get a helicopter ride from Brucie, there's an unsettling warning message about the helicopter on the inside of the cockpit that you can see if you look in first person mode.
• At the Firefly Projects,there is a swing,where if you drive backwards onto it,the swing will catapult you.

• In Star Junction there is sign for Love Fist. Love Fist was featured in GTA Vice City, and was also on a sign in GTA San Andreas.

On this website there is a discussion topic titled, "Jump to a new level of Spirituality" posted by "Trooth". This discussion thread includes more philosophical thoughts, mentions peyote, and provides a map of the Unique Stunt Jumps in Liberty City. These clues all suggest that the author of the email as well as the discussion topic is The Truth, a character from GTA San Andreas.
