Out of Commission

Out of Commission is the final mission of the "Revenge" ending in the of Grand Theft Auto IV. It is given to protagonist Niko Bellic from Little Jacob.

Mission
After Roman's and Mallorie's wedding, Niko 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 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 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 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 on fire but due to a rocket launcher so does the Annihilator. The two vehicles then crash onto Happiness Island where Pegorino runs under the statue, and Niko tracks him down, and kills him.

After killing him the credits roll and end with Niko saying "So this is what the dream feels like, this is the victory we longed for".

Deaths

Trivia

 * Shortly after, Niko will receive a call from Roman saying Mallorie is pregnant and if it is a girl, they will name her in Kate's memory. In the "Deal" ending, Mallorie reveals it to be a boy, but since both endings differ drastically, and follow different paths, this does not necessarily mean it is a boy in "Revenge".
 * A couple of days after completing the mission, Niko may receive a call from Kate. She will ask Niko to take her on a date, as if she never died. If Niko accepts, the date will function as normal. This is a glitch.
 * Even if you haven't got an AK-47, Niko will still hold one in the last cutscene and kill Jimmy Pegorino with it.
 * There is a flying rat under the ramp when you do the motorcycle stunt to grab the helicopter railing. It is pointless to kill it, as it you will, eventually, fail the mission.
