- "The Commission - the old families - I know some of those guys. And they thought you were a fat fucking joke."
- ―Niko Bellic, shortly before killing Jimmy Pegorino
In order to complete the mission the player must:
- Meet up with Roman and Jacob, who wait in a car in Alderney
- Follow Pegorino's goons, they'll lead you to Pegorino
- Pegorino is inside the old casino. Find him
- Chase Pegorino
- Get on the bike
- Chase Pegorino. Stick to the coastline, do not lose him
- Accelerate off the jetty to jump
- Get low and stay close to Pegorino
- Chase Pegorino
- Kill Pegorino
After Roman and Mallorie's wedding in the Revenge ending, Niko, who has been mourning the death of Kate, receives a phone call from Little Jacob telling him he and Roman found some of Jimmy Pegorino's mobsters in a building in Koresh Square in Alderney. Afterwards, the mission automatically starts as Niko goes to the two who are waiting in a Cognoscenti, and they begin to pursue the mobsters to Jimmy Pegorino.
After an extended car chase and dialogue between the three about why Niko is doing this, the two eventually lead them to an abandoned casino in the North of Alderney. Niko then fights his way into the casino, until he finds Pegorino. Pegorino states that if he would've worked for him things would be better, and Kate's death was Niko's fault. He then runs away and boards a boat on a jetty after letting loose more of his guards which are killed. He then gives chase by using a dirt bike and staying on the shore. After a short while, Roman and Jacob arrive in an Annihilator. Niko then jumps onto it by means of a ramp.
Once aboard he flies over Pegorino's boat with Jacob shooting at it. The boat catches fire but due to a Rocket Launcher shot so does the Annihilator. Jimmy manages to escape from the boat at Happiness Island and run under the Statue of Happiness while Niko safely lands the burning helicopter and goes after Pegorino. Niko then engages in a gun battle with Pegorino, mortally wounding him in the process.
A cutscene then shows Niko confronting Pegorino as he slowly bleeds to death. Niko tells him about knowing people in the Commission and that says they thought he (Pegorino) was "a fat fucking joke", Niko turns his back on Pegorino. As he raises his gun to shoot Niko from behind, Niko quickly turns back and shoots Pegorino in the head, killing him. Roman and Jacob then show up and comfort Niko. Roman explains that now that their enemies are beaten, they can start making money freely and live peacefully. Even though Niko agrees, he is still grieving due to Kate's death. Niko, Roman and Jacob then leave Pegorino's body at the foot of the Statue of Happiness as the camera pans out to show the Liberty City skyline at sunset.

After the Mission
- Niko receives a call from Roman, informing him that Mallorie is pregnant and that they will name the baby in Kate's memory if it is a girl.
- Niko receives a call from a tearful Packie, with Packie telling Niko that Kate didn't deserve to die as the McReary men were the "sinners."
- Following the credits, Niko says "So this is what the dream feels like, this is the victory we longed for."
Liberty Tree Newspaper
- "Police have found the body of Alderney mob boss, Jimmy Pegorino, on Happiness Island. Mr. Pegorino had captured headlines as the boss of a crime family with designs of power. They were thought to be seeking parity with the Five Families who had been weakened in recent years. After recent legal pressure and escalating bloodbaths in Alderney, crime pundits began to see Pegorino's crew as pretends, not the real thing. Police responded to reports of both a boat and helicopter crash on Happiness Island. Three suspects were witnessed leaving the scene and are being sought for questioning."
- The car chase scene in the very beginning of this mission is the only occasion when Roman complains about Niko driving fast. Usually he enjoys it and encourages Niko to drive faster.
- If the player fails to accelerate off of the jetty on the Sanchez, Pegorino will "escape" and the mission will fail. However, if the player looks at his boat after they fail the mission, they will see someone exiting the boat into the water. They can be followed onto land, and will be holding an AK-47. However, it is a random pedestrian, not Pegorino.
- Even if the player does not have an AK-47 their inventory, Niko will still hold one in the last cutscene and kill Pegorino with it.
- It is possible to dodge the final rocket that Pegorino fires but the player must be really high in the air and fly to the right near the bottom corner of Alderney. When it shows Jimmy fleeing from the boat the helicopter will be on fire even if the player dodged the last rocket.
- This is one of four final missions in the GTA series in which the main antagonist is not killed (the others being Freedom Flies in GTA Advance and Something Sensible/The Time's Come in GTA V) as in the Revenge ending Dimitri Rascalov was killed in A Dish Served Cold.
- If the player shoots Jimmy's boat with an RPG before entering the casino, the boat will be moved to avoid the explosion of the rocket.
- If the player manages to destroy the boat (by throwing grenades onto it), the mission will fail, with the onscreen message saying that Pegorino has fled.
- This is one of only two missions in GTA IV, (the other being A Revenger's Tragedy) that has a checkpoint the player can restart from if they fail the mission, which is when Niko are hiding behind the car. However, in this particular mission, if the player fails a number of times, the mission will restart from the beginning.
- If the player blows up the Sanchez with an RPG, it will not fail the mission then but when it says to get on the bike it will say the bike was wrecked and the mission will be failed.
- When Niko jumps into the Annihilator, if the player looks closely in the picture above, Roman is seen looking elsewhere and not aware of Niko's presence. And while Niko hangs, Roman isn't helping him, he just yells at him to climb up.
- When Niko jumps into the Annihilator, he closes the back door, and after that second, the door is open again. Outside the mission, the back doors are always seen open.
- The Annihilator is special in which it has a missing tail blade. This also occurs in A Revenger's Tragedy.
- Regardless of the speed Niko is travelling at when he rides the Sanchez off the ramp, it will still show him reaching a high enough altitude to jump onto the Annihilator.
- Pegorino will not begin riding away on his Squalo until Niko is within a certain distance and on foot. As such, it is possible, at the right angle and height, to shoot him with a sniper rifle while he's still on the boat. This has no effect other than a blood spray and random dialogue from Niko, as Pegorino can only die on Happiness Island.
- Before triggering the sequence in which Niko first confronts Pegorino inside the casino, the mission won't fail, no matter how long or far away he is from the casino. So it is possible to refresh ammo, health and body armor at any time and place before the chase begins.
