- The [Incomplete Control] Oppressor Demon King joins the battle
- Festival draw offers guaranteed hero rewards
- Introducing the Event Boss Parade and exclusive missions
Netmarble is celebrating a major milestone for The Seven Deadly Sins: Grand Cross (7DS) with its 5.5th Anniversary Holy War Festival. Players can welcome the new UR hero, [Incomplete Control] Oppressor Demon King, to their collection and explore a dedicated Hero Trial Story.
The latest update introduces the limited-time Ruler’s Return Festival Draw, where summoning milestones reward players with UR and SSR heroes. Reaching certain thresholds guarantees the [Incomplete Control] Oppressor Demon King, making it an ideal time to spend saved resources.
Following last month’s Solo Leveling collaboration, new activities include Special Missions, the Wish Box event, and the Event Boss Parade—offering Growth Materials, upgrade resources, and hero costumes.

For those seeking a challenge, the Event World Conquest tasks players with defeating Purinpu to earn event currency, exchangeable for additional rewards. Daily login bonuses further enhance the celebration, with up to 200 Diamonds available—plenty of incentive to dive in.
Join the action by downloading The Seven Deadly Sins: Grand Cross for free on Google Play and the App Store. The game includes optional in-app purchases.
