As it became known from social networks, Battlefield 6 players on PlayStation can earn up to 15% extra experience, while Xbox and PC users are limited to a maximum bonus of 10%.
On PlayStation, the experience bonus is distributed as follows: 5% for owning the game, another 5% for joining a group, and an additional 5% for participating in a group with two or more PlayStation Plus subscribers.
PlayStation users had a similar bonus system in Call of Duty, which is why many are not surprised by Sony's tricks in Battlefield.
