COSM-GAME StarSavior
StarSavior is a turn-based training RPG set in a fading world threatened by creatures from the Void. You play as a Captain who recruits star-powered fighters called Saviors and prepares four-character teams for battles built around skills, attributes, and turn order. A central training mode called the Journey lets you guide a Savior through schedules, rest, choices, and support cards called Arcana, shaping how that character develops before using the result in wider content. Story chapters, PvE challenges, guild activities, competitive battles, equipment growth, and character collection provide the long-term live-service loop.

Gameplay and setting
Players take the role of a Captain who recruits Saviors and forms four-character teams for turn-based battles. Each Savior has individual abilities, attributes, and traits, and party building focuses on combining those strengths while developing characters, equipment, and supporting Arcana.
The Journey is the central character-training mode. Players guide a Savior through schedules, rest periods, decisions, and events that shape how the character develops before using that trained result in other content. The setting follows the Nebula Observation Agency and its efforts to protect a fading world from Void threats, while long-term activities include Main Story chapters, Cosmo Gate, Guild Defense, Gauntlet, Flash Point, Interstellar Corridor, Hunt Quest, events, and other PvE and PvP challenges.
