Customizing weapons will play a part in successfully completing certain missions, lead mission designer Imran Sarwar told Game Informer. Extended clips/magazines, scopes, flashlights, suppressors and cosmetic alterations will let players tailor their armory to both their personal tastes, as well as the requirements of whatever gangster stuff they're about to perpetrate.
Likewise, car customization returns, though with reportedly more depth than the system seen in Grand Theft Auto: San Andreas. "Some missions ask you to customize vehicles in certain ways, and we have taken vehicle customization in general a lot further," Sarwar said. Cars and bikes can be outfitted with stuff as traditional as new body kits and paint jobs, to more miniscule alterations like changing tire smoke color, adjusting engine tuning and swapping out the vehicle's horn.
