Honor of Kings x Attack on Titan Free Rewards Guide: Flowborn Outfit, Heino Skin, and Collab Background

From May 1 to May 31, 2026, the international server of Honor of Kings (HOK) will host a limited-time Attack on Titan collaboration, offering players worldwide an immersive apocalyptic battle experience. This collaboration is exclusive to the international server.

The core highlights of this event are five limited skins and a Titan-themed map.

• Zhang Fei transforms into Eren, with his ultimate allowing him to become the Attack Titan.

• Jing corresponds to Mikasa, with skills featuring 3D Maneuver Gear effects.

• Yalian (releasing on May 8) becomes Levi, faithfully recreating his high-speed slashing.

• Ji Xiaoman matches Annie and can be obtained for free through the “Oath and Truth” event.

• Haino collaborates with Commander Erwin.

The map has been fully redesigned in the style of Paradis Island: high walls become Wall Maria, the dragon pit transforms into a Titan nest, the jungle is filled with Titan elements, and colossal Titan silhouettes can be seen on the outskirts. Coupled with exclusive background music, the sense of immersion is very strong.

Additionally, limited-time modes such as “Wall Defense Battle” are introduced, where players can randomly gain Titan transformation and other power-up abilities. Completing missions also rewards Wish Coins, themed sky scrolls, and other event items.

The Honor of Kings × Attack on Titan collaboration isn’t just about the major limited skins—it also offers several free rewards worth collecting. The Free Flowborn Collab Outfit becomes available on May 9 and can be earned by participating in Wall Defense and Armored Titan-related activities. Meanwhile, Heino · Scout Regiment Soldier and the Attack on Titan Collab Background are available from May 15 to May 31.

For players looking to join the collaboration on a budget, it’s best to focus on completing the free missions first. If you also want to collect additional limited skins and event items, plan your Token usage carefully and use UUTOP 👈to recharge your Honor of Kings Tokens as needed.

Free Flowborn Collab Outfit: Defeat the Armored Titan to Claim the Outfit

The Free Flowborn Collab Outfit is one of the most iconic free rewards in this collaboration. According to the event visuals, players need to participate in a Titan-themed Wall Defense event. The event description states: “Defeat the Armored Titan to claim a free collab outfit,” meaning players can earn this reward by defeating the Armored Titan or taking part in the wall defense activity.

Attack on Titan Collab Background: Background Wish Event

In addition to the outfit and skin rewards, this collaboration also features the Attack on Titan Collab Background. According to the event visuals, it can be obtained through the Attack on Titan Collab Background Wish event, which runs from May 15 to May 31.

The collab background is a cosmetic item—it doesn’t directly impact gameplay, but it’s perfect for players who enjoy personalizing their profile, lobby display, or event collection. The image showcases Eren and Titan-themed elements, with a fiery, intense atmosphere that perfectly matches the Attack on Titan collaboration.

Heino · Scout Regiment Soldier: Free Heino Collaboration Skin

The second major reward is Heino · Scout Regiment Soldier, available from May 15 to May 31. According to the event description, players will need to repel Titans and gather contribution points, suggesting that completing Titan-related missions is required to claim this reward for free.

Unlike the Flowborn outfit, this reward resembles what players typically consider a “hero skin.” Heino dons a Scout Regiment-style uniform, with a background featuring birds, a cloak, and scenery beyond the walls. The overall design strongly evokes the Wings of Freedom theme from Attack on Titan. For those who frequently play Heino or enjoy collecting free collaboration skins, this event should be high on your priority list.
