The Legend of Heroes: Trails of Cold Steel I originally launched on PS3 and PS Vita in 2013. In 2018, Falcom released Sen no Kiseki I: KAI - Thors Military Academy 1204 for PS4, later ported to PC (via NISA) and Nintendo Switch. The "KAI" (改) label means "revision" or "enhanced edition" – offering 60 FPS, high-resolution assets, and all previously released DLC.
