The AT-99 Scorpion mod for Grand Theft Auto 5 is essentially an addition of the Scorpion Gunship from the blockbuster movie Avatar. This mod gives the player the ability to fly around Los Santos in the Scorpion Gunship, providing a bird's eye view of the crime-infested landscape.

Designed and manufactured by RDA, the Scorpion Gunship is a ducted-fan VTOL (Vertical Take-Off and Landing) craft, primarily used for close air support missions. Powered by twin rotors encased in shrouds, this vehicle is known for its agility and speed. 

In terms of weaponry, the Scorpion is also heavily armed. It comes with two door-mounted GAU-90 thirty millimeter autocannons, with missiles that can lock onto enemy targets while being able to fire in an almost 360-degree field of view. This makes the Scorpion an excellent choice when undertaking mission with multiple enemy targets or in facing heavily armoured opponents.

Riding around Los Santos in this vehicle would offer a unique gaming experience, as it combines fast and nimble handling with heavy firepower. It also boasts of an impeccably detailed design, making it a truly lifelike and immersive addition to the Grand Theft Auto 5 universe.
