Netmarble has rolled out a collaboration update for its mobile RPG 'The Seven Deadly Sins: Grand Cross', developed by Netmarble F&C, featuring the TV anime 'Fire Force'.

'Fire Force' is a TV anime that follows a special fire brigade tackling the mystery of spontaneous human combustion to save humanity. This update introduces characters: the 'Hero of Flames' Shinra Kusakabe, the 'Crimson Cat' Tamaki Kotatsu, and the 'Frozen Time' Sho Kusakabe. The protagonist, Shinra Kusakabe, features damage reduction and enemy banishment skills. Each character's unique traits and concepts from the original anime have been faithfully reflected in the game.

A boss battle featuring the protagonist's brother, 'Sho Kusakabe', as an event boss is also available. By defeating the boss, players can collect resources to exchange for collaboration relic material boxes and Tamaki Kotatsu beauty costumes. Clearing the 'Extreme' difficulty 15 times grants the collaboration title 'The One Who Connects Adolla'. Additionally, the 'Hall of Warriors' has been expanded to 30 floors, rewarding players with a 'Skuld' costume upon completion.

Through the update's pickup summon event, reaching 600 mileage points allows players to select and obtain one of the new collaboration heroes. The collaboration attendance event offers up to 30 collaboration summon tickets over 3 days and up to 70 diamonds over 14 days. Completing the 7 special missions will reward players with growth materials and a costume for Tamaki Kotatsu.

The second benefit of the '777 Relay Campaign', which runs until June, has also been revealed. Along with Merlin and Escanor costumes and costume enhancement material coupons, mileage rewards have been boosted. Players can check a total of 7 benefits, including the Fire Force equipment supply box, upon reaching 60, 180, and 450 mileage points.
