From September 4 to September 6, you can receive twice as much XP and level up your operators, account, and clan faster, as well as move through a Battle Pass more swiftly.
During the Double XP event, you will receive:
×2 XP for participating in game modes.
×2 XP for Ribbons.
×2 XP for Medals.
Please note: XP from Medals only goes toward operator and clan levels; the bonus does not apply to Clan Battle Pass XP.
