7DS: Grand Cross Meets FIRE FORCE in a Fresh Crossover
Netmarble brings FIRE FORCE into The Seven Deadly Sins: Grand Cross with a new crossover. The event runs from January 29 through February 19, letting players explore a fresh set of characters. Three Fire Force heroes join the roster as SSR guests: Shinra Kusakabe, Tamaki Kotatsu, and Shō Kusakabe. Shinra is a flexible fighter who reduces ally damage and can banish one foe under certain rules. This makes him a key option that can shift the balance of fights.
