Interastra

Interastra is a space adventure about surviving across a mysterious planetary system. You explore planets, gather resources and uncover their secrets, then use a rocket to leave the planet you are on and venture further into the unknown.

Survival in space

You manage nourishment, hydration and oxygen while facing environmental threats that vary by planet. Temperature, weather and unbreathable atmospheres can put your survival at risk. You can avoid some dangers or create special equipment to withstand them, and must plan your journeys so essential supplies do not run out at the wrong moment.

Resources and your rocket

Each planet has unique supplies and resources for making new tools or upgrading existing ones. Gathering them can make survival easier and open new flight paths. As you progress, you unlock better rocket parts that let you direct your rocket farther through the planetary system.

Ruins and mysteries

You can explore ancient sites and ruins containing dangerous, unexplored areas, secrets and puzzle mysteries. Some rewards are worth the risks for those who persist.
