An Astronaut on a Forward Expedition is separated from their crew during a sudden and devastating attack by the Galactic Assault. Stranded and alone across unknown alien worlds, they fight through relentless waves of enemies — both the native inhabitants of foreign landscapes and the hunters sent by the Galactic Assault itself — while searching for survivors and working to repair the damaged ship. As the journey continues, a darker picture emerges: whispers of a full-scale invasion of the Astronaut's home city are growing louder. The return trip has never been more urgent, and the cost of failure has never been higher.
