Azur Lane has launched its latest limited-time event, Depths of the Astrarium, bringing five new Eagle Union shipgirls, additional skins and anniversary rewards to the naval shoot-em-up mobile game. The event runs until 26 August 2026. It forms part of Azur Lane‘s 8th anniversary celebrations, which also include login rewards, a new mini-game and an offline anniversary event in Los Angeles.
Players taking part in the anniversary Special Login event can collect daily rewards, with seven days of logins providing an opportunity to select one of eight shipgirls. Additional anniversary rewards being distributed to players include 900 Gems, one Promise Ring and a selection of resources.
The anniversary celebrations also introduce the Sealane Protector mini-game. Participating players can obtain Retrofit Items required to upgrade Belfast into her Ultra Rare Retrofit form. Five Eagle Union shipgirls make their debut through Depths of the Astrarium.
Players can earn event PT by clearing stages, with the Elite shipgirl John Rodgers available after reaching specified PT milestones. PT can also be exchanged for several rewards, including the Super Rare shipgirl Collett. She can additionally be obtained as a stage drop or through Limited Construction without a rate increase.
The Limited Construction pool features increased rates for three other new shipgirls. Super Rare shipgirls Bennington and Vicksburg are joined by the Elite shipgirl Harrison. A selection of new character skins has also been added alongside the event. Three dynamic skins are available, comprising Vicksburg’s Dazzling Diva of the Raceway, Fritz Rumey’s Verabredung in the Night Breeze and Essex’s Telepathy Training.
Additional skins include Collett’s Full-Auto Maintenance, Harrison’s Accidental Pursuit Race? and John Rodgers’ Grid Girl’s Interval. Three new L2D+ skins have also joined the game: Bennington’s Sunshine Chaser, Indomitable’s The Laid-Back Navigator and Musashi’s Cheering For You Alone. Previous skins are returning during the event as well, giving players another opportunity to obtain selected releases from earlier events. Returning L2D+ skins include Bois Belleau’s Steamy Therapy and Anchorage’s Sweet Evening Milk.
