Grand Theft Auto V is an action-adventure game played from either a first-person or third-person perspective. Players complete missions—linear scenarios with set objectives—to progress through the story. Outside the missions, players may freely roam the open world. Composed of the San Andreas open countryside area and the fictional city of Los Santos, the world is much larger in area than earlier entries in the series. It may be fully explored after the game’s beginning without restriction, although story progress unlocks more gameplay content. Players use melee attacks, firearms and explosives to fight enemies, and may run, jump, swim or use vehicles to navigate the world.[ To accommodate the map’s size, the game introduces vehicle types absent in its predecessor Grand Theft Auto IV, such as fixed-wing aircraft.
