Niko · Liberty City

Niko rescues Roman from kidnappers — emotional beat for IV's central duo.
Hostile Negotiation is a mission in given to protagonist Niko Bellic by Roman Bellic's girlfriend Mallorie Bardas via phone call.
This mission is connected to the mission Roman's Holiday in The Lost and Damned, where it is revealed that Roman was kidnapped by Johnny Klebitz and Malc on the orders of an employee of Dimitri Rascalov.
Niko receives a phone call from Mallorie Bardas, who informs him that she thinks Roman has been kidnapped and is being held hostage at the Xero Gas Warehouse in Industrial. Niko drives to the factory where Roman is being held.
Niko enters the factory and immediately takes cover behind a wall near the entrance. He fights his way through the factory, killing Dimitri's henchmen along the way, before finding Roman on the top floor. When he arrives, he finds Roman being held in a chokehold by his captor, who is holding a gun to Roman's head. Niko takes the kidnapper out.
Roman thanks Niko for saving him, and the latter follows the former to leave the warehouse. Niko drives Roman back to his apartment in South Bohan. When they arrive at the apartment, Roman admits the extent of his gambling addiction. Niko also explains that the duo need to leave Bohan as quickly as possible before Dimitri comes looking for them.
