Secrets and Easter Eggs in GTA IV


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

Secrets
On the west side of Happiness Island, there is a random spawn that can be a car. This is unusual as there is no way a vehicle can be brought on to the island unless unloaded by a ship.
 * Car on Happiness Island

Behind an old, run-down mansion in Westdyke, Alderney at the end of the dirt roads, there is a hidden and extremely rare Sultan RS parked in some bushes. This is practically the only way to find the car in-game. The only other way to obtain it is if the game has it stored in the temporary memory (perhaps because one appeared in one of Brucie's Races), and automatically spawns it parked or driving around the streets.
 * Sultan RS behind an abandoned mansion

If the player's vehicle has been damaged to the point that the engine has stopped, calling any number on the mobile phone will start it again. This does not work if the car is incinerating.
 * Re-start a breakdown vehicle by phone

Easter Eggs

 * Face of the statue & the Hot Coffee

The Statue of Happiness's face bears a striking resemblance to former U.S. Secretary of State Hillary Clinton. This resemblance, along with the cup of coffee in her right hand, may be a reference to the Hot Coffee controversy which Clinton took investigation in, also suggesting that new regulations be put on video games.
 * "No Hidden Content This Way" sign

The southern door has a sign: "No Hidden Content This Way". This is similar to the sign on top of the Gant Bridge in GTA San Andreas and The Hidden Sign in GTA III. Within the Statue of Happiness is a giant beating heart, supposedly the "Heart of Liberty City." In GTA IV, access into the area is only achievable via an entrance marked by a "No Hidden Content This Way" sign at the upper level of the statue's pedestal, which can only be reached by helicopter. Once inside the pedestal, the player must scale a ladder up to the midsection of the statue, where the heart is located. It can be shot at, but nothing happens. In The Ballad of Gay Tony, if Luis drinks too much and blacks out, he will wake up at random locations after the black screen, one of which may be the Heart of Liberty City.
 * Heart of Liberty

There's an unsettling warning message about the Maverick inside the cockpit that can be seen if the player looks in first-person mode. It implies this: "This helicopter might crash but we really don't care if it does, refer to flight manual for help."
 * Maverick's warning message

If the player positions the camera in such a way that the player is able to see inside Packie's head, a small cube with Packie's balaclava texture from Three Leaf Clover can be seen.

In the graveyard behind the Meadows Park Church, there is a tomb or cenotaph with the epitaph below: ''Roll of Honor "War of the Deadline" 1869-1869 "for those about to build...... we salute you"''. This is a reference to the album titled "For Those About to Rock We Salute You" by AC/DC.
 * Tomb of Meadows Park Church

 * Photocopier in TW@

While driving the Mr. Tasty, the player is able to trigger songs to play by clicking the horn. One of these songs is the theme song of GTA IV. While this song is playing, call ZiT and they will text back with "ZiT! Spotted GTA IV Theme". This resembles a cheat that gives the player health, armor and ammo, but this will also block some achievements and trophies in the game.
 * Mr. Tasty & the GTA IV theme music

In the backyard of Mikhail Faustin's home, there are two blood trails on the ground.
 * Blood trail behind Faustin's house

There is an easter egg in The Libertonian; the plaque describing the Tyrannosaurus Rex and Triceratops. The texture of the text is low-resolution, and thus hard to read properly, but reads, roughly: "This big bastard took a few days to knock up because it had to be done by the sole hand of a prop artist. But alas, and feast your eyes on this 21000 poly maniac. Trex right up your arse. How do you like them apples?".
 * Plaques of the fossils

 * In the night sky

Easter eggs references to previous games
On the staircases in most apartment blocks in the game, the player may spot some graffiti referring to past protagonists set in GTA III canon (Claude, Tommy, Carl (CJ), Toni, and Vic), that suggests they have died, though it is likely metaphorical as GTA III canon is over so they won't be seen again. The only on-screen death of a protagonist so far is Victor Vance and Johnny Klebitz. The graffiti is intended to serve as "a little joke for fans of the series", as a different design approach to GTA IV meant the games' timeline could only inherit various fictional brand names and certain radio personalities; it is, however, no indication as to whether or not GTA III canon has been retired.
 * The "RIP/we'll miss you" graffiti

Paint One Building depicts artworks of previous GTA titles as graffiti on its walls, including characters from Grand Theft Auto III, Grand Theft Auto: Vice City, and Grand Theft Auto: San Andreas.

 * Miniatures in Miniature Golf Course

On Happiness Island, in front of the entrance to the statue, it is possible to find a street-artist's easel/display stand with several pictures. These pictures are all concept works of many previous GTA characters. The easel can also be seen in south-central Algonquin, very close to where Hossan's random encounter takes place and in front of the The Libertonian.
 * Street-artist's artworks display

There are signs scattered throughout Liberty City that say "Hot Coffee Shop", clearly a reference to the Hot Coffee sexual content and controversy from GTA San Andreas.
 * Hot Coffee in Liberty City

One of the TV shows is a program called The Venturas Poker Challenge. It features a casino in Las Venturas from GTA San Andreas. When shown, the commercial doesn't have GTA IV graphics and art, it features GTA San Andreas graphics, the most obvious being the building designs and taxi. Similarly, footage of the Vinewood sign from GTA San Andreas is used for Vinewood Cunts TV ad; it is recognizably San Andreas animation due to the transmission tower visible right behind it, which was also in the earlier game. GTA San Andreas is also used for Patriot 500 TV commercial. The CNT reality show I'm Rich also uses some footage of GTA San Andreas.
 * San Andreas on TV

Niko can receive an email from Chiliad8888, which calls the recipient "Pilgrim", makes many spiritually- and philosophically-charged (and anti-government) comments, ends with "Feel the Truth, Live the Freedom", and links to whattheydonotwantyoutoknow.com. 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.

In the mission Final Interview, if the player shoots the guard standing at the top of the last flight of stairs when escaping from Goldberg, Ligner & Shyster, he will do a Wilhelm Scream as he falls down. This does not always happen in the PC version however. At the beginning of Clean Getaway, Vlad is nearly hit by a taxi and shouts "Hey! I'm walking here!" in reference to the movie Midnight Cowboy. When the player harms a cop sometimes they will shout "I'm gonna be okay!", referring to Reservoir Dogs, when Mr. Orange is shot in the abdomen and is screaming in delirium. If the player goes on a Heli Ride with Brucie, and when reaching the Rotterdam Tower, Brucie might say "If I was that big chimp, I would climb it too." This is a reference to King Kong.

Bugs & Glitches
While playing multiplayer, some of the TVs in safehouses and the TV in the MeTV building, show the game's pause menu without the map. At the Firefly Projects, there is a park with a swing set. If the player drives backwards (or forwards with some vehicles such as a Voodoo) onto it, the swing set will catapult the vehicle high in the air. This is likely a bug in the game's physics simulation. See Swing Glitch article for more details. Normally hostile pedestrians will flee. Go into any strip club and either shoot it up or spend some time with a stripper. Then go to areas where there are gang members that will become hostile if they are bumped. Punch them and they will run away. Drivers that normally would get out and try to harm the player if the player punches or hits their car will also flee. This only has a temporary effect.
