Sure, Superman, Spider-Man and The Flash entered the world of Grand Theft Auto V ahead of him, but now that Tony Stark has shown up, he's at this car-punching, repulsor ray-firing, missile-launching, high-flying best.
In the new PC mod -- it's the work of JulioNB, who earlier added the character to GTA IV -- Iron Man exchanges Stark Tower for the mean streets of San Andreas, where he proceeds to wreak havoc in the grand tradition of the hit game franchise.
Not someone known for his moderation, Stark unleashes his armored-encased fury on passing vehicles and patrol cars alike. And when someone pulls a gun? Iron Man responds with a missile. Seems reasonable.
