One Last Thing is the final mission given to Niko by Jimmy Pegorino, and is the final non-optional mission. It's not actually a mission, just basically a cutscene and the player determining which ending to take.
In order to complete the mission the player must (after witnessing the cutscene and making the two post-mission phone calls):
- Make your decision (go to the Deal icon or Revenge icon)
In the cutscene, Niko relaxes at the mini-bar inside the club. Pegorino walks up to him and explains that he is ordering Niko to do a deal with his nemesis, Dimitri Rascalov. Remembering how Rascalov first introduced Niko's old rival Ray Bulgarin to him back in Broker, then literally burned Roman out of Hove Beach, and finally how Rascalov kidnapped Roman -- Niko is extremely reluctant to do the deal. Pegorino orders Bellic to meet Phil Bell at his apartment to do the deal.
The cutscene ends and Niko goes outside the strip club. He phones his cousin Roman. Roman tells Niko he knows all about the deal and also knows the hideout of Dimitri. Niko realizes that now he can just kill Dimitri and forget about the deal. Roman begs against this and thinks Niko should leave his life of violence behind and get the money, with it Roman says he can afford a great honeymoon with Mallorie and even get a private jet so he and Niko can go to Vice City. Niko phones Kate. She advises Niko to steer clear of the deal. Kate doesn't think he should sacrifice his principles for money, and tells Niko he should not take his chances with Rascalov.
Now, it is time for one of the two Endings in GTA IV to commence. Two icons (a green dollar sign and a red dagger sign) will appear on the map (in Tudor and the Broker docks respectively). The final choice the player must make in the game's storyline is now left to the player; will you strike a deal with Rascalov or exact revenge on him? Before going to start either mission, you may want to go stock up on weapons if you haven't already.
It is recommended that you, if you are playing on AutoSave, that you create a secondary save file after this mission so that you can experience both endings quickly.
- This is the only cutscene where Niko drinks alcohol, ordering "Vodka on the Rocks" most likely because he didn't know Pegorino was going to give him a briefing, but also possibly because of what he had just been through (See Niko Bellic/Personality for more).
- When Niko orders vodka on the rocks, he is given a normal glass cup with some vodka in it. Normally, vodka on the rocks is vodka poured in a fancy glass with ice cubes and a lemon.
