On the meter, the displayed stars indicate the current wanted level (for example, at the maximum six-star level, efforts by law enforcement to incapacitate players become very aggressive).Law enforcement officers will search for players who leave the wanted vicinity.
There is a first-person perspective option when using vehicles.
In combat, auto-aim and a cover system can be used as assistance against enemies.
Should players take damage, their health meter can be fully regenerated using multiple techniques, such as eating, using medical kits, or calling for paramedics.
If players commit crimes while playing, the game's law enforcement agencies may respond as indicated by a "wanted" meter in the head-up display (HUD).
Outside of missions, players can freely roam the game's open world, and have the ability to complete optional side missions.
Composed of the fictional city of Liberty City, the world of Grand Theft Auto IV is larger in area than most earlier entries in the series.

A sequel, Grand Theft Auto V, was released in September 2013.
The wanted meter enters a cooldown mode and eventually recedes when players are hidden from the officers' line of sight.
Melee attacks include additional moves, such as dodging, blocking, disarming an opponent and counter-attacking.
At the beginning of the game, players can only explore the first island–composed of Dukes and Broker–with all other islands unlocking as the story progresses.
