New Clan Battles season, Trade-in and more - Closed Test 13.4

Ahoy, Captains!

We can't believe it's already time to share some information about Update 13.4! They just grow up so fast, don't they?


Clan Battles Season 25: Polar Bear

We hope you haven't stored away your winter coats yet, because Season 25 of Clan Battles will be called Polar Bear! Come warm up by the fire while you check out this season's format:

  • 7v7
  • Tier X ships
  • No Submarines or Aircraft Carriers permitted
  • Maximum of 2 Battleships per team

To gear up for the occasion, we have added an achievement for the teams that end the season in the Top League, as well as an achievement for the winner!

  • Polar Bear
  • Hurricane. Polar Bear

Now, this season is going to be a bit shorter compared to recent ones, lasting from May 20th until June 10th, with battles beginning on May 22nd.  We've heard some feedback that players want Clan Battles to feel a bit more fresh and exciting, and we're definitely onboard with that! As a result, we wanted to test out a feature that could help positively shake up the Clan Battles: Support Consumables.

For those that have played the Piñata Hunt battle type, this idea will be somewhat familiar: There will be a selection of Support Consumables available (no unlocking required!) that are designed to make interactions between players more interesting and unique. The only consumable not present from Piñata Hunt will be the Iron Curtain consumable. Feel free to check out the list of consumables below!

Activating the Call Smoke Curtain, Call Patrol Bombers, Drop Minefield, and Coordinated Fire consumables opens the Tactical Map: there, you can choose the area to deploy the selected consumable. For Coordinated Fire, you'll need to select an enemy ship instead of an area.

In order to keep teams balanced with these Support Consumables active, there will be restrictions on which classes can take certain consumables. You can check those out in the table below.

 Support consumables restrictions

Destroyer   Call Patrol Bombers   Drop Minefield   Joint Fleet Maneuvers   Coordinated Fire   N/A
Cruiser   Coordinated Emergency Repairs   Forced Stalemate   Drop Minefield   Coordinated Fire   N/A
Battleship   Coordinated Emergency Repairs   Call Smoke Curtain   Forced Stalemate   Call Patrol Bombers   Joint Fleet Maneuvers

In addition to the above restrictions, Divisions will also be limited to two of each consumable per division. Use them wisely! 


Do you have some ships that you don't use anymore? Are there some ships that you want but can't afford right now? Well never fear, because the Trade-In feature is here once again!

For two weeks, starting from the last week of Update 13.4, a special tab will be available in the Armory where you can exchange certain Tier V-X premium and special ships for a significant discount on the purchase of other premium and special Tier V-X ships with doubloons. Rare ships that are difficult or impossible to obtain are exchanged for a larger discount. Additionally, we have expanded the list of ships that players are able to exchange including ships that can be obtained for Research Points and Steel.

If the ship you exchanged offers a discount greater than the value of the ship you want to purchase, then you will get that ship without any additional payment! Be careful though - the difference in value is not compensated, so make sure you're getting the best bang for your buck.

Lists of ships that players can receive:

 V Siroco,V Genova,V Agincourt,VI Gallant,VI Dupleix,VI W. Virginia '41,VII Yūdachi,VII Flint,VII Florida,VIII Kidd,VIII San Diego,VIII Brandenburg,IX Minegumo ,IX Dalian,IX Karl XIV Johan,X Forrest Sherman,X Napoli and X Max Immelmann
