Short answers, pulled from the story.
Suikoden Tactics is a tactical role-playing game developed and published by Konami for the PlayStation 2. It is the first strategy-based entry in the Suikoden series, replacing the turn-based combat of earlier games with grid-based tactical battles where terrain elements and positioning play a central role.
Suikoden Tactics was initially released in Japan and North America in late 2005, then in Europe and the PAL region in early 2006. It was published exclusively for the PlayStation 2.
The music was composed and arranged by Norikazu Miura, a series veteran who also composed the Suikoden V soundtrack. The opening theme, "Another World," was performed by Japanese vocalist yoshiko.
Suikoden Tactics sold approximately 64,472 copies in Japan within its first year. That figure qualified it for a re-release under Sony's "PlayStation the Best" budget label in November 2006.
The game follows a young man named Kyril investigating mysterious weapons called Rune Cannons. The story unfolds in two parts: a prologue set roughly seven years before Suikoden IV and a main narrative set three years after those events, taking Kyril into the Kooluk Empire.
Critics gave the game mixed reviews in the West, with Metacritic categorising them as "average." Reviewers widely praised the grid-based battle system but criticised the story, voice acting, and graphics. Famitsu scored it 31 out of 40 in Japan.
