After purchasing the Verdant Meadows Airfield, Toreno informs Carl that he is going to be taking flying lessons. Carl initially refuses, but once Toreno claims that this will help secure his brother's release from prison, Carl relents and agrees to the task. Toreno explains that he has set up a television screen showing the ten lessons Carl will be completing. After completing all ten missions successfully, Carl receives his pilot's licence. Grand Theft Auto: San Andreas is an action-adventure video game developed by Rockstar North and published by Rockstar Games. It was released on 26 October 2004 for PlayStation 2, and on 7 June 2005 for Microsoft Windows and Xbox. Grand Theft Auto: San Andreas is an action-adventure game with role-playing and stealth elements. Structured similarly to the previous two games in the series, the core gameplay consists of elements in a third-person shooter and a driving game, affording the player a large, open world environment in which to move around. On foot, the player's character is capable of walking, running, sprinting, swimming, climbing and jumping as well as using weapons and various forms of hand-to-hand combat. The player can drive a variety of vehicles, including automobiles, buses, semis, boats, fixed-wing aircraft, helicopters, trains, tanks, motorcycles and bikes. The player may also import vehicles in addition to stealing them. The open, non-linear environment allows the player to explore and choose how they wish to play the game. Although storyline missions are necessary to progress through the game and unlock certain cities and content, they are not required as the player can complete them at their own leisure. When not taking on a storyline mission, the player can freely-roam and look around the cities of San Andreas, eat in restaurants, or cause havoc by attacking people and causing destruction. Creating havoc can attract unwanted and potentially fatal attention from the authorities. The more chaos caused, the stronger the response: police will handle "minor" infractions (attacking pedestrians, pointing guns at people, stealing vehicles, manslaughter, etc.), whereas SWAT teams, the FBI, and the military respond to higher wanted levels. The player can partake in a variety of optional side missions that can boost their character's attributes or provide another source of income. The traditional side missions of the past games are included, such as dropping off taxi cab passengers, putting out fires, driving injured people to the hospital and fighting crime as a vigilante. New additions include burglary missions, pimping missions, truck and train driving missions requiring the player to make deliveries on time, and driving/flying/boating/biking schools, which help the player learn skills and techniques to use in their corresponding vehicles.
