In the real world, ships started making use of signal flags as a method of communication because it’s easier to fly a flag than to try to shout to other ships. World of Warships had to include these flags, naturally, but the flags serve more of a purpose than simple communication in a game that features a chat function to begin with. No, the signal flags still serve to communicate because they’re functionally gear for your warships.
Sets of flags can be earned in a variety of ways; players can earn a set of flags that will swiftly put out fires, for example, when a ship goes down due to a fire on deck. Aside from providing the benefit, the flags also will communicate the ship’s immunity to other players. It’s an interesting system, and one that you can learn all about in the video development diary embedded just below.
