About Sigma Star Saga DX
Sigma Star Saga DX combines side-scrolling space-shooter battles with top-down planetary exploration. You play as Ian Recker, a pilot in the Allied Earth Federation who infiltrates the alien Krill Empire as a double agent in a last-ditch effort to save mankind.
The double-agent mission
With loyalties divided between humans and Krill, you investigate six planets using tools and abilities that expand as you progress. The branching story has multiple endings and includes a secret to discover across the planets.
Explore and fight
On the planets, you explore from a top-down perspective and use tools such as the Scanner, Krill Boots and Wings. In space, you pilot your ship in side-scrolling combat and customize it with more than 70 Gun Data items, which yield over 15,000 combinations. The game also features boss battles and pixel-art graphics.
DX enhancements
Sigma Star Saga DX refines the 2005 release with an improved map, a lower random encounter rate, a rebalanced EXP system, enhanced dialogue and an updated script. It also adds save points, bug fixes and other quality-of-life updates.
