Russian Revolution is the last mission for Dimitri Rascalov in Grand Theft Auto IV. Dimitri is supposed to pay Niko his reward for executing Mikhail Faustin. The mission is triggered by calling Dimitri to find out if he has Niko's money. Large scale shootouts are introduced as well as cover system and blind fire.

• Niko and Dimitri are scheduled to meet in an East Hook warehouse so Niko can collect his money for Faustin's execution. He requests that you meet him in the abandoned warehouse alone. Little Jacob questions Dimitri's motives and insists on accompanying him in the background. 
• Meet Jacob behind the warehouse.
• Watch the cutscene in which Dimitri tries to have you killed. Dimitri is working with Ray Bulgarin. Niko knows Ray from dealings in Eastern Europe that went sour and still owes him money. 
• Take cover, and take out the five men in the area.
• Continue forward, picking up body armor and weapons as more enemies enter.
• Stay behind cover and pick them off.
• Head up to the top floor and take out additional enemies there.
• Keep picking up weapons.
• Run to the exit of the warehouse as the cops arrive on the scene. Take out as many as you can so Jacob does not get killed.
• Steal one of the cop cars to get away with Jacob. 
• Head to the park near the taxi depot to lose the wanted level.
• Drive Jacob back to the Homebrew Cafe to end the mission and unlock Roman's Sorrow.
