About this game
Space Battleship Story RPG merges side-scrolling space battles with long-term Earth base development.
As commander of the Unified Earth Forces, you clear sectors, return resources to Earth, and upgrade ships and weapons. As in-game dates advance, Earth grows and the warfront expands from the solar system toward the galactic core.
Story
From Earth you are tasked to lead humanity's push into space.
After the prologue, Earth City opens as your hub, and you sortie into the solar system—Moon, Mars, and worlds beyond. Each cleared sector reveals more of the unknown.
Eventually you cross the solar system, alien regions, wormholes, and the galactic core. Beyond the main climax lie the edge of spacetime and fates shaped by your choices.
