The Machine Gun is a weapon featured in the 2D Universe games.
The machine gun name was first seen in Grand Theft Auto 1 for use by an unknown assault rifle-like firearm that is capable of firing larger numbers of bullets within a period of time than a pistol. Because of this trait, the machine gun is far more effective in flooding an area with bullets, increasing the chances for the player to hit targets quicker. However, as the weapon fires a large number of bullets at a time, its ammunition may deplete faster than the player would expect for a pistol. The weapon's rifle design in GTA 1 is also incorporated for use in the game's flamethrower.
Subsequent depictions of the machine gun, in Grand Theft Auto: London 1969, Grand Theft Auto: London 1961 and Grand Theft Auto 2, would undergo several changes in terms of their physical appearance, but generally retains the traits of its predecessor in GTA 1.
In GTA 1, the machine gun seems to be based on the Spectre M4. For both GTA London games, the machine gun is modeled after a Sten Mk II, which has its magazine on the left side of the gun. In GTA 2, the machine gun's damage per bullet was decreased to only half that of the pistol, and is given the appearance of a sub machine gun, being referred to in the game as a S-Uzi Machine Gun, a clear reference to the Uzi name. In addition to a conventional S-Uzi, GTA 2 additionally offers a "Silenced Machine Gun" that features a suppressor intended to muffle the sound of gunfire. In addition, machine guns can be mounted on cars, and the Armed Land Roamer comes with its own form of mounted machine gun. The icon of the gun appears to be a TEC-9 pistol without a barrel shroud and a shorter barrel. It is advertised twice, on Funami FM and Lithium FM.
