Cosmic Star Heroine is a role-playing game developed by Zeboyd Games, available on the Nintendo Switch platform. The game features Alyssa L'Salle, a secret agent at the Agency of Peace & Intelligence on the Planet Araenu, who goes rogue to save the galaxy from a horrible conspiracy.

The game has a mix of classic and modern RPG elements, with a brisk pacing that respects your time, and allows you to save anywhere. The battles take place directly in the areas that you explore, with no separate battle screen. The 2D visual style is reminiscent of the 16-bit era, and the animated cutscenes are reminiscent of the Sega CD & Turbo Duo era. The soundtrack by HyperDuck SoundWorks is over 100 minutes long.

Cosmic Star Heroine has an innovative turn-based combat system that focuses on flow and strategy. The game features multi-character combo techniques, and your own spaceship to recruit new agents to help your home base grow.
