About Aethernaut

"

Aethernaut is a first person puzzle game set in an open steampunk world. Guided by the voice of Cornell, a scientist who claims to want to help you, you are tasked with solving various puzzles to progress and reach the deeper areas of the Construct. 

Choose how the story unfolds based on your answers to Cornell’s philosophical questions, as he seeks to better understand your nature and personality. Would you rather be remembered forever as an evil tyrant, or be completely forgotten? Is happiness or usefulness a more important purpose in life? When we fall in love, do we love the real person or just our idea of that person?

Through your answers, you will discover yourself and learn more about your past, and how you are able to survive the deadly aether. 

But there is more to the story. As you delve deeper into the abandoned Construct, an unseen entity tries to make contact with you, and begs for your help. Who will you trust? Who are you, really?

STEAMPUNK PUZZLES

Solve puzzle rooms using light, sensors, portals and time travel to gather the aether vials and access the core of the Construct.

EXPLORE THE CONSTRUCT

Discover hidden secrets within the Construct. Jump, climb, and use the portals to reach new areas.  

UNLOCK YOUR STORY

How will you answer Cornell’s questions? His increasingly personal queries will prompt you to reveal your personality, which will in turn shape the story around you. With 6 possible endings, depending on your answers and how you solve the puzzles (or if you do at all!) Aethernaut will unlock the depths of your soul.

How much does Aethernaut for PC cost right now?

Aethernaut for PC starts at €5.68 at Kinguin, a Steam key, which is 66% under the €16.49 it costs on the official store.

That €5.68 already includes the AUGGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Just 7 stores stock it, 7 offers in all, so there is little here to push the price either way.

That puts it 4% under its average of €5.89 since 2022, so today is a better entry point than most days of its life.

Can you activate it in your region?

6 of the 7 offers work on US — the Global ones plus the ones issued for your own region.

So, which Aethernaut deal should you buy?

€5.68 at Kinguin is the one to take.

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

It is a key that will allow you to download the game Aethernaut on your PC from official download platforms.
As of 02/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Aethernaut on PC is €5.68.
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 Aethernaut 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 Aethernaut, 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.

A first-person steampunk puzzler stylized like Portal. Use light, portals, and time powers to explore a mystery of a Construct. Solo-developed and bloody-mind-f#$kery - the steampunk mechanics stand out but there are probably a few bugs to fix first.
