What is the key for Sirius Online on PC?

It is a key that will allow you to download the game Sirius Online on your PC from official download platforms.

What's the best price for buying the key of Sirius Online for PC?

As of 05/12/2025, in United States, the best price we have found in our selection of online stores that include the key for Sirius Online on PC is €7.61.

Which digital format of Sirius Online should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

If I buy the account format of Sirius Online , will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Why is the Steam Key of Sirius Online safer than the account format?

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 Sirius Online to your game library. The account format requires more complicated steps and is more prone to errors during activation.

What issues can arise when activating a Steam Key of Sirius Online ?

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 Sirius Online , and they will provide a new key. You can also contact us, and we’ll help you out.

How long will I have to wait to receive the Steam Key of Sirius Online after purchasing it from a store?

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.

What guarantee do I have that the listed stores are reliable?

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.

Some digital formats allow returns under certain conditions.

The store does not send my order and does not respond to support. What can I do?

Don't worry, we have the solution. We will handle it ourselves.

The final price is higher than indicated.

Many stores add payment fees, taxes,... in the cart. So be prepared to spend a little more.

I'm desperate: They don't send me the game, the store ignores me. I think I've lost my money.

About Sirius Online

War. A never ending source of waste. A never ending demand for more lives and resources. The Year is 2436, and humanity, once again, wages war on itself. Nearly a hundred years ago we settled on the Sirius Star System, a rich system with two habitable planets. The first Settlers, now forming the Sirius Colonial Council built this ecology from the ground up. They self-governed and prospered. Five years ago, the Terrans appeared, demanding to return the Control over the System. Failure to do so would result in catastrophic response from the Terran Reclaim Forces.

And so, once again, war erupts.

Take part of the war or live along both sides, trade, fight, think and explore. Be the tip at the iceberg of the upcoming conflict. Control the Economy with your Trading Craft. Find unimaginable riches in our galaxy quadrant. Battle Pirates and even more sinister forces. Create your own Empire among the Stars.
