An orange T-shirt that has "100%" written on the front will appear in Franklin's closet. Players can witness multiple UFO sightings at Mount Chiliad, Fort Zancudo, and Sandy Shores.
With so many main missions to be completed, players will always bring home some cash for each mission. However, the true prize of Grand Theft Auto 5 comes in the form of its Story Mode Heists, which will easily see the player get money faster than other activities like robbing ATMs or convenience stores.
