ExoTrain description

ExoTrain — Adventure on a Ruined Colony

You take on the role of an engineer who lands on a distant planet to work in a colony once built by Exoplanet Industries. Instead of a thriving settlement, you find only ruins and scattered remnants. Your goal is clear: survive, explore, and uncover the story behind the collapse of the outpost.

Drive the train to traverse the harsh world and push your journey forward. The locomotive is not just transport—it’s your lifeline. You can upgrade the train and expand its capabilities, building what you need to reach new areas, haul resources, and endure the voyage across hostile terrain.

Fight to survive in a world where wildlife is extraordinarily dangerous, yet it also serves as a critical source of food and raw materials. Every encounter tests your skills and your readiness to adapt to a frontier where danger lurks behind every ridge.

Explore the colony ruins to search for resources, clues, and answers about what happened to the settlement. Scattered structures, abandoned equipment, and forgotten data await your investigation as you piece together the planet’s history.

Mine and defend ore veins as you extract vital materials. Mining noise draws attention from predators, so you must set up turrets and other defenses to protect the drill and your haul. Balancing extraction with protection becomes a core strategic challenge.

Gather resources to craft equipment, protective gear, and spacesuit modules. Collect the right materials to upgrade your tools, enhance survivability, and tailor your loadout to the dangers you face on this world.

Play solo or coop with friends and share the risky, rewarding journey. Whether you prefer a solitary survival vignette or a collaborative push through the ruins, ExoTrain supports both play styles as you push toward discovery and endurance.
