Battle royal is "the" thing these days and many games are including it as a secondary game mode. The latest to do so is World of Warships thanks to the addition of Rogue Wave: Sink Them All. Four teams set sail for a post-apocalyptic "desolation-themed port" with destroyers tailed specifically for this event. Captains take the fight to one another as an "enclosing Wall of Fire forces close-quarters brawls" in an effort to be the last ship...er...sailing.
Captains can earn Fuel Tokens, in-game items, "expendable camouflage" for completing missions. There are also four Directives with eleven missions total. Completing all will net captains the V Hill ship.
In addition, improvements have been made to matchmaking, Clan Brawls are on the way starting July 6th, the Ranked Battle Sprint 6v6 is on its way and some changes have been made to the current season.
