For the second time now, World of Warships have begun another crossover event with the vtuber group, Hololive.

This time around, personalities Shishiro Botan, Moona Hoshinova, Watson Amelia, and Takanashi Kiara will come in to fill the roles of commanders.

This coincides with update 12.3 for World of Warships, which also introduces a new map along with Pan-American cruiser ships.

Here’s the rundown trailer:

Here’s a rundown of the 12.3 update:

Sail into the Seychelles
Expanding the horizons of Warships’ waters, a new map of the tropical Seychelles Islands has been introduced in Update 12.3. Bearing strong resemblance to the mountainous islands of Praslin and La Digue, this new, leafy green map will be available for both Random and Co-op Battles. Ships spanning Tier V-IX can compete in Domination mode with four key areas, scattered across the map in two different variations.

A New Allied Heroes Collection
World of Warships also welcomes a themed “Allied Heroes” Collection in dedication to the end of World War II in Europe. With 12 different elements to collect, players who complete each section will be rewarded with corresponding Commanders for the allied nations, each equipped with 10 skill points. These elements can be found through new “Allied Heroes” containers, which are obtainable for credits and free XP in the Armory. Sitting at the end of the entire collection is a redeemable three-days of Warships Premium Account.

Say Hello to hololive production
Closing out Update 12.3’s content drop, hololive production characters make a return to the game. Four Japanese virtual bloggers (VTubers) join the ranks of Commanders. Choose from different commanders including Watson Amelia and Takanashi Kiara, who are each equipped with their own unique voiceover, to take the helm in battle. Alongside these new additions, this partnership also introduces a special expendable camouflage and a commemorative flag.

This update also brings several bug fixes, upgrades and balance changes across the game.

World of Warships is available now for PC (via Steam and the Epic Games Store).
