There are many hit missions in Grand Theft Auto IV, and Niko Bellic has accrued the greatest body count of any GTA protagonist thus far, with over 80 possible named murders. This is most likely because he works as a hired gun instead of a creating a criminal empire and because GTA IV has named most chracters instead of going after unnamed thugs.
The following is a list of his intended targets ("collateral" murders such as those of unidentified gunmen, pedestrians, or police are not included), including random characters, Most Wanted, optional killings and possible killings he may attempt.

Choose between two targets
- Playboy X or Dwayne Forge - Both characters ask Niko to kill the other.
- Francis McReary or Derrick McReary - Niko can shoot either with his sniper rifle; again, both have asked Niko to kill their opposite number.
- Mickey - Can be killed during Uncle Vlad.

- Vasily - Niko can kill him in a drive-by in the mission Wrong is Right.
- Karen - Can be killed during Final Interview.
- Alonzo - Niko can kill him, or let him warn Teddy.
- Stevie - If the player is quick enough they can kill him after I'll Take Her. He may or may not be the Stevie Niko does the car thefts for.
