Play Sigma Star Saga (GBA) Online Free

Sigma Star Saga is a unique genre-blending game by WayForward that combines a top-down RPG with side-scrolling space shooter mechanics. Players take on the role of Ian Recker, a double agent infiltrating the alien Krill Empire. As Recker explores planets in RPG mode, random encounters transport him into a shmup (shoot-'em-up) battle inside a spaceship. The game features a deep weapon customization system using 'Gun Data' collected from enemies. With a mature sci-fi story, multiple endings, and excellent pixel art, it is a cult classic on the system.
