The events of Suikoden Tactics take place three years after those detailed in Suikoden IV, making it both a spin-off in the Suikoden series and a direct sequel to Suikoden IV. The plot of the novel focuses on the events that took place following the conflict between the Kooluk and the Island Nations, as well as the mystery surrounding the beginnings of the Rune Cannons. Kyril, the main character, is a powerful young warrior who is continuing his intense fixation with the Rune Cannons, which he inherited from his father. Kyril’s father was obsessed with knowing as much as he could about the Rune Cannons.
The previous Suikoden games were action-oriented role-playing games, but Suikoden Tactics is a tactical role-playing game. Large-scale, tactical combat are the primary focus of the game, and there is no opportunity for exploration; yet, traditional role-playing game aspects such as character development and equipment advancement are also present. The battle system is very similar to that of Fire Emblem. Players have the opportunity to strengthen their alliances with one another throughout the course of the game, which makes for an effective combination strike. During combat, if two different characters talk to each other, it will boost their fighting compatibility with each other. The majority of the gameplay focuses on several talents and spells that may be leveled up and improved. The narrative cutscenes are played with voiceovers and are rendered in real time.
