You saved the innocents of Gradius from the vile Bacterions. But now an even deadlier plague has infiltrated the neighborhood. It's Zelos, a planet-eating alien who is thirsty to eat you!
But this time, you don't have to save the millions of Gradians alone. You can call on a starfighter friend from the planet Latis, who will fight alongside you in his RoadBritish space destroyer. You'll both go for max power-ups, with ripple lasers, plutonic missiles, and impregnable force fields. But you better be on target.
Because he's not your ordinary space scum. And to crush him, you must soar through his guts, bypass his deadly traps, and ultimately blast his heart out. Good luck, commander. The galaxy is counting on you!
