SEGA AGES Lightening Force: Quest for the Darkstar

From the legendary game developers at Technosoft!

Battle against the Vios forces and fly as RYNEX in this side-scrolling
shmup that enthralled the world with its innovative ideas, beautiful
pixel graphics, and a rocking soundtrack.

After beating the game, unlock "STYX" Mode and jump in the cockpit of
the distinguished FIRE LEO-03 "STYX" from Thunder Force III. Take the
STYX’s full arsenal from the previous game in this mode, but will this
older model be able to survive?
