Arknights 5.5th Anniversary Launches New Events & Operators

• The anniversary celebration runs from July 17th to August 14th, introducing new story stages.
• Four new Operators join the roster for the first time.
• Players receive a free 10-pull ticket, anniversary outfits, and upgrade packs.

Arknights launches its 5.5th Anniversary with the event "Such is the Joy of Our Reunion," a content-rich celebration lasting until mid-August. This global update brings a fresh story campaign, time-limited rewards, four new Operators, and a selection of premium cosmetics, all delivered in classic Arknights style.

Central to the event is the Tianshi Bureau narrative, unfolding across stages such as Agricultural Plate, City Core, and Far Side of the Great River. Completing stages and commissions rewards you with Sky Poles, which can be traded at the Shennong Market for materials, resources, and the free 5-star Operator Wanqing. 

Key rewards include Elite Materials, Headhunting Permits, LMD, and a complete themed furniture set for your base. Additionally, the login bonus campaign, available until July 31st, grants a free 10-pull on the An Eternity Aflame banner, offering a chance to obtain new Operators led by the limited 6-star Yu. 

Yu is a durable Defender who inflicts Burn and Arts damage, self-heals, and reduces Elemental Injury. Joining him is Blaze the Igniting Spark, a 6-star Caster with a versatile damage-and-healing kit and a revival ability that lets her recover from near-defeat with a stunning burst.

Two new 5-star Operators also debut: Xingzhu, a support unit providing Sanctuary and healing while dealing Arts damage, and Surfer, a Vanguard with rapid redeployment and ranged attacks. Her unique trait grants bonus DP when deployed alone, rewarding strategic placement.
