Which digital format of Firmament 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 Firmament, 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 Firmament 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 Firmament 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 Firmament?

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 Firmament, 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 Firmament 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.

Calm down, don't panic. Contact us and we will help you resolve it as soon as possible.

About Firmament

ABOUT FIRMAMENT

Firmament is a new puzzle-adventure game by the legendary game studio behind the best-selling games Myst and Riven. Featuring deep storytelling and world-building, discover the story of this seemingly abandoned world as you explore and unlock the mysteries of 3 unique Realms… and beyond!

EXPLORE THE WORLD

Featuring a unique steampunk aesthetic, Firmament invites you to explore the legendary deep world-building Cyan Worlds is known for. Firmament is a fantastic visual feast, with thrilling new sights to see around every corner. At the same time, the world of Firmament feels completely plausible; as though it were constructed with a bigger purpose in mind… A purpose you will be compelled to discover as you play.

SOLVE THE PUZZLES

You carry with you a device called an “Adjunct” as you explore. This Adjunct is your interface as you interact with the various devices throughout the Realms of Firmament. Employing the Adjunct to solve the puzzles you encounter will bring you ever closer to unlocking the secrets this place holds.

DISCOVER THE STORY

You are not entirely alone in Firmament. In addition to The Adjunct, you are joined by a mysterious apparition, who has a story of her own to share with you. As you explore you will be introduced to 3 Realms - each with secrets and mysteries to reveal. What purpose do the Realms serve? Can the spirit who accompanies you be trusted?

REVEAL THE MYSTERY

Are the realms of Firmament abandoned? What are these giant, mysterious machines scattered throughout the world? What is their purpose? What part do you play in this grand mystery? Explore, Discover, Solve, and Reveal the mystery for yourself by playing Firmament!
