Hello, everyone.
2K is going to be sunsetting Mafia III: Rivals' servers on March 7th, 2019, which will disable all gameplay in the app. After this point, players attempting to load Mafia III: Rivals will receive a "Network Error" message. Mafia III: Rivals is no longer available on app stores and Credits are no longer available to purchase.
You can still spend any Credits you have before the shutdown date.
