About StarRupture
StarRupture drops players onto a mysterious planet where recurring cataclysms constantly reshape the landscape. The open world is rich in resources, places and secrets to discover, demanding continual exploration and adaptation in a dangerous environment that is constantly reborn.
Survival hinges on building a complex industrial system, extracting and processing resources, and defending a base against aggressive alien hordes. You can face the planet alone or team up with up to four friends in online co-op. The Steam listing also notes features such as custom volume controls, playability without timed input, saving at any time and Steam Cloud.
01 / THE GUIDE
Open World & Cataclysms
The planet is torn apart by repeated cataclysms, creating a dynamic open world that feels reborn after each event. The vast world is rich in resources, places and secrets, encouraging repeated exploration.
Because the environment is ever-changing, players should expect the landscape to surprise them at every turn and plan their routes and activities around a world that will not stay static.
- Re-explore familiar areas after cataclysms to find resources and secrets.
- Treat the planet as constantly changing and adapt your plans rather than relying on fixed routes.
02 / THE GUIDE
Industrial System
Players search, mine and process resources to develop a complex industrial system that produces goods and supports base expansion. New technologies can be unlocked to help you and your base survive the harsh conditions on the planet.
The industrial network is central to survival, since extracted and processed resources underpin the structures and equipment needed to endure extreme temperatures and other challenges.
- Unlock technologies steadily so your base can handle the planet's harsh conditions.
- Keep extraction and production balanced so your base expansion never stalls.

03 / THE GUIDE
Combat & Alien Hordes
Aggressive alien creatures attack in hordes, and players must defend themselves, their team and their base. Combat is a core part of surviving on the planet, alongside building and exploration.
Defense works best when structures and teammates are positioned thoughtfully, whether you fight solo or coordinate with co-op partners to protect shared facilities.
- Prepare your base defenses before alien hordes arrive.
- In co-op, decide in advance who defends which part of the base.
04 / THE GUIDE
Multiplayer Co-op
StarRupture can be played alone or in a group of up to 4 friends in online co-op. Sharing building, resource gathering and defense duties can speed up industrial development and strengthen base protection.
Working as a group encourages coordinated planning and dividing responsibilities, which helps the team survive everything the harsh planet throws at them.
- Divide responsibilities among players, such as mining, building and defense.
- Agree on group goals before cataclysms strike so the team can react together.
