Sigma Star Saga is a 2005 hybrid science fiction role-playing-space-shooter developed by WayForward Technologies and published by Namco for the Game Boy Advance.

The story focus on a space pilot named Ian Recker who goes undercover against Earth's enemies, the Krill, in a battle to save the planet.

A re-release of Sigma Star Saga is scheduled to arrive in 2025 for PC, Game Boy Advance and modern platforms.

[4] There are two distinct portions of the game: an overworld where the player control Recker directly, and side-scrolling shooter random battles.

In the overworld, Recker travels around either talking to people to advance the plot or searching for items and data on one of several planets.

The ship battles are where the RPG elements of the game come in: as the player kill enemies, they drop experience bubbles, which power up the offensive and defensive capabilities.

Much of the game revolves around the shifting relationships between Recker's female companions: the Krill pilot, Psyme, and the human scientist, Scarlet.
