"I got two options. Option one, you ripped me off. Option two, Luca and his buddies ripped us both off."
Ray Boccino

Meltdown is a mission in Grand Theft Auto IV given to protagonist Niko Bellic by Ray Boccino.

Mission objectives

In order to complete the mission, the player must:

  • Go to Castle Garden City.
  • Chase after Luca's gang. You need Luca alive to get the diamonds back.
  • The gang have escaped into the park. Take them down.
  • Luca is hiding in the toilets. Flush him out.
  • Take out Luca.
  • Pick up the diamonds.
  • Go meet Ray on the bridge.


From Drusilla's, Niko heads to the waterfront district of Castle Garden City where Luca's car is located. As Niko approaches the car, Luca can be overheard discussing a trip to Las Venturas. Niko confronts Luca, Johnny, Tuna and an unnamed fourth passenger, about the missing diamonds, but Luca feigns innocence and claims he gave them to Ray. Taking offense to Niko, Luca and crew race off to tell Ray that it was Niko who actually stole the diamonds. Niko steals a nearby Banshee and chases them through Star Junction. When they eventually reach Middle Park, Luca veers off into the park itself, when shortly after they lose control, crash into a statue, spin out of control and slam into the side of a large fountain. 

With the car wrecked, Luca and his crew escape on foot. Luca flees into the toilets and the rest of his crew hide behind pillars just outside waiting to shoot at Niko. When Niko kills the three accomplices he goes into the toilets to find Luca. Niko soon learns that Luca has hidden himself if one of the toilet stalls, so Niko shoots down the locked doors one by one until Luca is found. Luca attempts to bribe Niko with a cut of the diamonds in return for sparing his life, but Niko executes him.

Afterwards, Niko calls Ray only to find out that his job was to simply just retrieve the diamonds, not kill Luca. Niko brushes it off and then meets Ray on the Quartz Street bridge over Middle Park where he gives back the diamonds.

GTA 4 - Mission 61 - Meltdown (1080p)


  • Joseph DiLeo - Murdered for stealing diamonds from Ray Boccino.
  • John Barbosa - Murdered for stealing diamonds from Ray Boccino.
  • Luca Silvestri - Murdered for stealing diamonds from Ray Boccino.
  • Luca's unnamed henchman - Murdered for stealing diamonds from Ray Boccino.


  • When the player arrives at the waterfront in Castle Garden City, the Banshee will not be there until the cutscene plays.
  • No NPCs are actually in the toilet stalls. When the doors are shot open, two tramps will spawn inside them; the third will always be Luca.
  • There is also a mission in GTA V named Meltdown.


  • (PS3 only) The Middle Park glitch may occur during this mission. They whole terrain of Middle Park will disappear, which means when Joseph, Jogn, and Luca crash, they will fall through the map But once the cutscene ends, they will appear in the middle of the street in Middle Park West. So it is impossible to find Luca in the toilets.
  • On some occasions, after killing Luca in the toilet Niko will just stand there with the cinematic view and the player will be stuck in the cinematic view and Niko can't be moved, therefore the mission can't progress (Discovered on PC)
