Murders Committed by Niko Bellic

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 murders. This is most likely because he works as a hired gun instead of a creating a criminal empire. Here is a list of his intended targets ("collateral" murders such as those of unidentified gunmen, pedestrians, or police are not included). Random Character, and Most Wanted kills are also choices. Enemy-friend kills are choices that the player can make. These include characters who play a role in the storyline. When given the choice an arrow that blinks red (for enemy), or blue (for friend) will appear. Possible murders are murders of people that don't have a major role in the game, or any role at all.
