After closed showings by Rockstar Games, details about the artificial intelligence of characters have emerged. For example, the physical fitness of police officers will affect the effectiveness of pursuits: among them, there will be overweight officers who will tire faster and may stop during a foot chase, breathing heavily and leaning on their knees.
The behavior of residents will also become more diverse. Upon seeing a weapon, some will be frightened and run away, while others will try to disarm the hero. Defeated enemies may drop clothes and accessories – these can be picked up and used for quick camouflage.
Changes will affect robberies and random events. A vendor under threat may reveal a hidden safe, and on the streets, players can intervene in the crimes of other robbers and take their loot. Pedestrians' clothing will match their surroundings – from sportswear near gyms to everyday wear in poorer neighborhoods.
