How much does Ostranauts for PC cost right now?

Ostranauts for PC starts at €9.43 (€10.53 with fees) at Kinguin — that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €26.44 (€27.71 with fees) at Key4Games.

That €9.43 (€10.53 with fees) already includes the OCTGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Only 5 offers across 3 stores carry it, and thin supply means the price barely moves.

Is it worth buying the Steam Key for Ostranauts now or waiting?

That €26.44 (€27.71 with fees) key is expensive for what it usually costs.

  • Those €26.44 (€27.71 with fees) are 200% above what it usually costs, measured on the store price.
  • Only 1 stores sell the Steam Key, and with that little competition the price barely moves.
  • Across the 172 days we have tracked it, it has only been pricier than today on 0 days. The lowest it has ever cost is €2.60.
If you do not need it today, waiting pays off: we have seen it at €2.60 and right now you would pay €23.84 more. We will tell you the day it drops.

Worked out from 199 daily records of the Steam Key for Ostranauts across 4 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.

Which Ostranauts format should you buy?

With the shared account at Kinguin 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 Key4Games costs €17.01 (€17.18 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.

The 2 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.

Can you activate Ostranauts in US?

4 of the 5 offers work on US — the Global ones plus the ones issued for your own region.

Do you want to buy Ostranauts for PC cheaper than in official stores?

Then from Gocdkeys, we recommend that you go for the digital version of the game. The digital versions of the PC games are available in cd key or digital code format, a quick and easy method to download games from the official download platforms such as Steam, Epic Store, Uplay and Origin, among many others.

What is Ostranauts 's cd key?

The cd key, or STEAM Key, is a digital code that will allow us to download the Ostranauts  game in our PC from the Steam game platform. A series of numbers and letters that when introduced in our library of games will allow us to download this game in digital form.

How can we find the cheapest price for the Ostranauts STEAM key?

That's our job and we do it very well! From Gocdkeys we offer a comparison of prices and stores that sell the digital version, in the form of code, STEAM key or Steam Gift of Ostranauts . Simply enter the list and you will see all prices ordered from lowest to highest, so it will be easier to find the best deals and prices in a complete selection of online stores specializing in the sale of digital games. 

You can use our filters to filter by versions or activation regions, to make it easier to find the cheapest Ostranauts edition that best suits your needs.

Can I trust the shops that sell Ostranauts in digital version?

At Gocdkeys we have been working for years to make sure that only the most reliable stores appear in our game price comparator. Each and every one of them has been checked by our team and they offer the best guarantees that the whole process, from the purchase to the delivery of the game keys, is done in the fastest and easiest way possible.

What digital versions of Ostranauts are available?

Although from Gocdkeys we indicate that this is the cd key, it can also be available in "Steam Gift" format which means that instead of receiving a code or digital key after purchase, we will receive an activation link, which will activate the game directly in our game library. Steam Gifts can be regionally locked, so please pay attention before purchasing this version.

You will see on a label, next to the price, the version or edition that is sold in each of the stores. If none of them appears, it means that it is a standard version of the game and in digital key format.

What do I do after buying the Ostranauts key in any of the stores that appear in Gocdkeys?

Now it's time to activate the game! Right after your purchase in any of the online stores listed in our platform, you will get in your email the digital code or key of the game. After that, and always depending on the version of the game you have bought (cd key or Steam Gift) you will have to enter this key in your "Game Library", in "Add product" and in a matter of seconds the download of the game will start.

If it's a Steam Gift version, simply log in to your account and click the activation link that we've sent you in your email.

Before you buy Ostranauts  you should know that...

Ostranauts is a space life simulation game in which the player must choose a ship captain from a wide selection. Depending on the previous trajectory of that captain, we will start with a series of advantages or extras for our ship. 

Once on board, the player must manage the compartments of the ship, as these can wear out or, if you want, you can add new compartments and make the ship bigger. Keep discipline with the food, in space there are merchants but you don't want to be in debt with them. In addition, you will be able to enjoy a complex system of depth in the AI characters since they are programmed to act in relation to how a person who lives in space and learns from their previous experiences would do it. In addition, you will be able to interact with all the other worlds in a totally capitalist galaxy where commerce and marketing are the cornerstone.

Most common FAQs when buying Ostranauts for PC in digital format:

It is a key that will allow you to download the game Ostranauts on your PC from official download platforms.
As of 24/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Ostranauts on PC is €26.44 (€27.71 with fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Ostranauts to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Ostranauts, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
