INTERASTRA is a space adventure with a content struggle for survival. Explore a mysterious planetary system and discover its secrets. Everybody will experience a survival simulation, where taking care of their essential needs is a challenge. Exploration and resource gathering ultimately lead to leaving the planet you're on, venturing further into the unknown. Take on various environmental threats, from different temperatures and weathers to unbreathable atmospheres.
Besides darkness, outer space hides many threats, so plan your journey into the unknown. You need to maintain optimal nourishment and hydration levels and make sure you have an ample supply of oxygen, as wrong choices can cause them to run out at the worst moments. In INTERASTRA, you will experience different threats, depending on the planet. You may avoid certain dangers or create special equipment to withstand them.
Each of the planets has unique supplies and resources that can create new tools or upgrade existing ones. Gather them to access new flight paths and make your survival easier. Thanks to the power of a space rocket, explore the entire planetary system. As you progress, you will unlock new and better rocket parts, allowing you to direct your space rocket further and further.
Get ready for mysterious places with various puzzle mysteries. The ruins hide unexplored areas full of dangers and secrets that only the wisest will solve. For the persistent, some rewards are definitely worth the risk. Are you brave enough to explore the ancient sites of an old civilization?
How much does INTERASTRA for PC cost right now?
INTERASTRA for PC starts at €6.41 (€6.91 with fees) at Key4Games, 40% under the €11.59 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €11.59 (no fees) at Steam.
This is the lowest price it has ever been recorded at.
That €6.41 (€6.91 with fees) already includes the GOCDKEYS16 coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 3 offers from 3 stores — and thin supply keeps prices steady rather than falling.

Worked out from 1,031 daily records of the Steam Key for INTERASTRA across 2 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Are these stores safe to buy INTERASTRA from?
One caveat worth €0.30 (€0.10 with fees): the €6.41 (€6.91 with fees) at Key4Games is the cheapest, but that store carries only 37 Trustpilot reviews, so there is barely any track record behind it. Difmark sells the same shared account for €6.71 (€7.01 with fees) — €0.30 (€0.10 with fees) more — backed by 14.2k reviews and a 4.1 out of 5, which is a small premium for a seller thousands of buyers have already tested.
Which INTERASTRA format should you buy?
With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Steam costs €5.18 (€4.68 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
Can you activate INTERASTRA in US?
All 3 offers are Global, so the code redeems on any account no matter where it was created.
