Most Wanted

The Most Wanted missions are side missions in Grand Theft Auto IV in the same vein as the Vigilante missions from the 3D Universe games.

Description
When stationary in a law enforcement vehicle such as a Police Cruiser, the player can access the Police Computer and see the top ten criminals wanted by the LCPD for the current borough. The player is then able to select any of the ten listed criminals to pursue, the target will show up on the map and the player must drive there and eliminate the target(s). There is no time limit, and the missions can be re-attempted if failed.

There are thirty most wanted criminals in the game - ten in Algonquin, ten spread across Broker, Dukes and Bohan (which are counted as one borough by the police computer), and ten in Alderney City in the neighbouring state. If the player chooses a target that is too close to their current position, the mission won't start and the police computer will say "The profile is being updated". Once a mission is completed, the name is marked in red in the most wanted list - if the player tries to undertake the mission again, the police computer reports that the target is deceased, and the mission cannot be started.

Many of the targets have friends which also need to be eliminated to successfully complete the mission. Like many other missions in the game, many of the targets stay in a static location and fight Niko Bellic, but in several cases, they try to escape (depending on which mission is being played). Completing all of the most wanted missions is required for 100% completion of the game, and unlocks the achivement Manhunt.

The ability to use the Most Wanted list is unlocked in the mission Crime and Punishment, but if the player miraculously guesses one of the names listed below, the option "Search Police Records" can be used to find the target at any time.

State of Alderney
Alderney City (Acter, Tudor, Berchem, Normandy and Leftwood)

Trivia

 * The name of the achievement, Manhunt, is a likely reference to the Rockstar series Manhunt.
 * Marking a waypoint on the target, then taking a taxi there makes your journey quicker and it won't matter that you don't have police car, as the game simply prompts you to "Take out all the targets".
 * If the player tries to start a Most Wanted mission while already at or too close to the target's location, the screen will say, "Updating Server", and will continue to do so until the player moves away.
