The Criminals within the city of San Paro are the driving force behind the primary game activity within APB. The idea is that the Criminals prey on the city they prey on the civilians, they prey on the cars, they prey on the businesses and the Enforcers are sent out to try to stop them.
If you're working for the Criminals, you'll report to The Blood Roses and the G-Kings. These two NPC criminal organizations will issue players objectives and missions. These can range from anything to stealing a car to robbing a bank, or taking on a bounty set against another player who has gained a particularly high reputation. While carrying out these objectives, a player’s actions dictate what occurs throughout the rest of the world. For example if a group of gangsters attempt to steal a car, but triggers the car alarm, nearby Enforcers are alerted by and APB, and the objective changes to get away without being taken down.
As Criminals become more and more successful they take over areas of turf within the districts, and they are given bigger jobs and better heists when they have more turf at their command. They are at a constant war with other criminal gangs for this turf, and the system allows criminal factions to fight against each other. When these altercations escalate enough or cause issues within the city, APB’s are sent out to the appropriate number of Enforcers that are ready to handle this situation, effectively creating a three-way encounter.
