Gamescom: WoWS Lootbox Mechanic

At Gamescom we were shown a new opportunity for World of Warships – WoWS Lootbox. Developers would like to implement this until the end of the year, but it may come at the beginning of next year. Nothing more is revealed! Will the gift boxes fall out for good games or if they will for ranked battles – or be only for purchase – not known. The particular box awarded 7 flags.
