You probably could've guessed this part: GTA 6 will bring back the series' wanted system. You'll still build up stars as police try to take you down ever more aggressively, but Rockstar's making some notable tweaks to the system in order to encourage players to play in different ways.
"The wanted system in GTA 6 requires that someone witness the crime, or an alarm needs to be set off for it to be reported to the law," Rockstar North co-studio head Rob Nelson tells IGN. "One star is not going to be too difficult to get away from. You can see with these little icons on-screen, the police know what we're driving, so we should just jump out of the vehicle. They also know we're a couple. You could split up, and that will also help lower the police’s perception of you."
