Netmarble applied the 'Perfect 7' Legend Festival update on the 21st to commemorate the 7th anniversary of the mobile RPG 'The Seven Deadly Sins: GRAND CROSS' (hereinafter 'The Seven Deadly Sins: Grand Cross'). Development was handled by Netmarble FNC.

The centerpiece of this update is the new hero, Meliodas, the sworn enemy of 'The Seven Deadly Sins'. This character uses the 7-person combined technique 'Unbreakable Heaven,' which appeared during the final battle with the Demon King in the original anime. When the ability is activated, the character switches to Assault Mode for 1 turn to inflict massive damage. When the ability is not used, 'Trillion Revenge,' which provides damage reduction and counterattack effects, is applied, allowing for situational operation between offense and defense. The Survey Summon, held to coincide with the 7th anniversary, was organized based on user voting results. It features 7 types of UR-grade heroes, including a new hero, and 39 types of SSR-grade heroes. Upon reaching 777 mileage points, you can choose and obtain one of 7 LR heroes. If you collect 900 mileage points, you can acquire 'The Seven Deadly Sins' Unbreakable Heaven Meliodas. Various events have also been prepared alongside the update. You can receive up to 300 diamonds just by attending for 28 days, and you can obtain growth resources such as the 'Transcendent Ban's Emblem Halo Costume' by completing World Quests. A special mission event is also being held where you can receive growth resources, Jumping Box Tickets, Merlin & Escanor's Emblem Halo Costumes, and more by completing 19 missions. The '777 Jumping Box Event' is also being held, providing heroes, growth resources, King & Diane, and Gowther's Emblem Halo costumes in stages. Clearing the four event bosses allows you to obtain Jumping Box Tickets, 7th Anniversary Card Packs, and Crystals of Time, and the 'Solgales Grand Reward Dungeon,' which offers daily rewards, is also in operation. At the 7th Anniversary Party Hall set up within the game, you can obtain rewards through mini-games and receive up to 100 summon tickets per day through the Lucky Draw. It is also possible to check your play records through the 7th anniversary infographic 'Beautiful Gluttony'. In addition, a 77-floor 7th anniversary Tower of Trials event is underway, and Chapter 5 of 'The Four Horsemen of the Apocalypse' has been added. New PvE content, 'The Supreme Temple', is also included in this update. To mark the 7th anniversary, a special PV video and a new OST titled 'Perfect Time', featuring voice actor Yuki Kaji, have been released on the official YouTube channel. Users who participated in the 7th anniversary pre-registration will receive rewards such as a UR Hero Selection Ticket and 77 Diamonds. 'The Seven Deadly Sins: Grand Cross' was released in Korea and Japan in 2019, launched its global service in 2020, and has surpassed 70 million cumulative downloads worldwide to date.
