In the distant future, the galaxy is in a state of intergalactic conflict between human civilization and the enigmatic alien race known as the Oxel. During an exploration mission to the remote planet Umtu, a Human Alliance spaceship mysteriously disappears near the Oxel border.

The captain of the missing ship, brave astronaut Alex Ren, is adrift in space, fighting for his survival while trying to send a distress signal. At the same time, it is discovered that the ships hijacked by the Oxells contain vital technology for the defense of the Human Alliance.

It is at this critical moment that the player assumes the role of intrepid space pilot, Cadence Steele, assigned to the mission to rescue Alex Ren and recover the ships hijacked on the planet Umtu. Equipped with an advanced combat ship and strategic ingenuity, Cadence ventures into enemy territory, facing dangerous alien creatures and technological challenges to accomplish her mission.

Once the risky undertaking is complete, Cadence must head to the nearest allied space station to report on the success of the mission and receive new orders to protect the galaxy from future Oxell threats.
