Seven Deadly Sins Grand Cross GACHIAKUTA Collab Goes Big

Seven Deadly Sins Grand Cross GACHIAKUTA is now live, bringing a fresh collaboration update to Netmarble’s cinematic mobile RPG. The new event adds four SSR collaboration heroes, special missions, login rewards, boss battles, and the final phase of the long-running 777 Relay Event.

For players who enjoy anime crossovers, this update has plenty to chase. It mixes new characters, free rewards, and limited-time activities into one packed event.

Seven Deadly Sins Grand Cross GACHIAKUTA Adds Four SSR Heroes

The collaboration introduces four new SSR heroes from GACHIAKUTA.

The new lineup includes:

• [GACHIAKUTA Team] Cleaner Rudo
• [GACHIAKUTA Team] Cleaner Enjin
• [GACHIAKUTA Team] Cleaner Zanka
• [GACHIAKUTA Team] Cleaner Riyo

Players can obtain these new heroes through the special The Seven Deadly Sins X GACHIAKUTA pickup draw.

In addition, the event gives players several milestone rewards. At 100, 200, 400, and 500 mileage points, players can receive 10 pickup tickets once per milestone. At 300 mileage points, players can receive one SSR hero from the draw lineup. Then, at 600 mileage points, players can choose one of the four collaboration heroes.

Login Rewards Include Diamonds and a Free Hero

The Seven Deadly Sins Grand Cross GACHIAKUTA collab also includes special login events.

Players can receive up to 77 Diamonds during the event period. They can also obtain [GACHIAKUTA Team] Cleaner Zanka through the Part 1 and Part 2 login events.

That makes the event easier to enjoy even for players who do not plan to spend heavily. With a free collaboration hero and diamond rewards, the update gives both returning and active players a reason to log in daily.

Special Missions, Bingo, and Boss Battles Are Available

Netmarble also added several limited-time activities for the collaboration.

The special mission event asks players to clear eight missions. Rewards include collaboration Holy Relic material boxes, upgrade materials, and more. Players who complete all eight missions can also receive a Holy Relic enhancement material box.

Meanwhile, the special bingo event lets players use bingo currency earned through gameplay to unlock rewards. These include collaboration special boxes and additional upgrade materials.

Players can also challenge the collaboration event boss, Hanjoo. By clearing boss stages and exchanging event currency, players can earn more rewards, including Holy Relic material boxes and upgrade materials.

Those who clear Extreme difficulty 15 times or more can also receive an exclusive title.

Tower of Trials Adds New Floors

This update also expands the Tower of Trials.

Floors 31 to 45 are now available. Players who clear Floor 45 can receive a costume for Oslo & Hawk.

This gives long-time players another challenge to clear while the collaboration events are running.

777 Relay Event Reaches Its Final Phase

The update also marks the seventh and final phase of the 777 Relay Event.

Players can redeem the coupon code 777ENDAND to receive Legendary Seals x77 and Skip Tickets x77.

Netmarble is also offering a costume for Gowther of the Seven Deadly Sins as a campaign reward. New and returning players can still receive rewards and benefits from earlier phases of the 777 Relay Event.
