"Battlefield V is made to reward how often you play and how well you play. You will never be able to use Battlefield Currency or spend real-world money to get anything that gives you an unfair gameplay advantage." Which is a nice change of pace after the whole Battlefront 2 debacle. With Battlefield V, EA and DICE will not be selling an additional Season Pass - instead all new gameplay content will be free.
Which leads to a progressions system called Company - which serves as the game's economy too. Company Coin will be earned via playing the game and can be spent to further customise items outside of the basic progression path and also to purchase cosmetics. An additional real-world money version called Battlefield Currency is expected to come after launch, but will only be tied to cosmetic items.
Battlefield Currency will not be available at launch. We want players to get hands-on experience with their Company, the progression system, and earning Company Coin before introducing premium currency.
Balanced rock-paper-scissors gameplay has always been the foundation of the Battlefield series, and our belief is that real-world money should not enable pay-to-win or pay-for-power.
