The Heart Of Liberty City is a gigantic beating heart located inside of the Statue of Happiness. It is held up with chains, and there appear to be various arteries and veins going from the heart to the statue's exterior. Shooting at it or throwing explosives at it will make it spurt blood, but it will not trigger any other response.
In The Ballad of Gay Tony, the protagonist Luis Fernando Lopez may spawn inside the statue next to the heart if he passes out drunk.
The door that the player must walk through to access the Heart is on the upper platform of the pedestal. The player cannot reach the platform by stairs, and must jump from a helicopter, or parachute onto the platform. Once on the platform, there will be four doors around the base of the statue. There is a small sign next to the non-solid door reading "No hidden content this way." A bloodstain can be seen in The Ballad of Gay Tony outside of the non-colliding door. The door does not have any collision, and the player can just walk through it. Inside of the statue there will be a long ladder. Player should climb up the ladder and they will access another platform inside the statue, and the giant heart will be hanging from chains.
- This is believed to poke fun at all the towns that have locations called "The Heart of ..."
- It seems that entering into the Heart's room is needed for 100% completion, as a Flying Rat is found in the statue, which reveals itself when the player uses a rocket launcher in the area.
- This may be a possible reference to Oscar Wilde's 'The Happy Prince'.
