Which digital format of Mars Horizon 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 Mars Horizon, 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.

Can I return a digital game for PC?

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.

Q: Why is the Steam Key of Mars Horizon 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 Mars Horizon to your game library. The account format requires more complicated steps and is more prone to errors during activation.

How much does Mars Horizon for PC cost right now?

Mars Horizon for PC starts at €3.26 at Driffle, a Steam key.

That €3.26 already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.

The listing shows 15 offers from 8 stores, though only 13 can be bought at this moment — the price above comes from those.

That puts it 4% under its average of €3.38 since 2020, so today is a better entry point than most days of its life.

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

That €3.26 key is at its usual price: no bargain, no spike.

Those €3.26 are 11% below what it usually costs, measured on the store price.
Only 7 stores sell the Steam Key, and with that little competition the price barely moves.
Not counting today, 647 days out of the 1,312 days on record were this cheap or cheaper; the lowest it has ever cost is €1.02.

It is not a bad price, but it is not this Steam Key's floor either. If you are in no rush, we will tell you the day it drops.

Worked out from 1,981 daily records of the Steam Key for Mars Horizon across 16 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 Mars Horizon format should you buy?

By format: Steam Key from €3.26 and Steam Gift from €19.53.

Can you activate Mars Horizon in US?

10 of the 15 offers work on US — the Global ones plus the ones issued for your own region.

Is Mars Horizon worth it?

Critics put it at 74 out of 100, though there are only 12 reviews published so far.

Why is there such an expensive Mars Horizon offer?

One listing is worth ignoring: the Steam gift that G2A has at €22.15 is more than 6 times the cheapest offer and is not what this game costs. The number to work from is €3.26 at Driffle.

So, which Mars Horizon deal should you buy?

Get it now: the cheapest key is at Driffle for €3.26 and the game stays on your own account.

The lowest we have ever seen is €1.02, so waiting is unlikely to give you much more than you already have today.

WHAT IS THE CD KEY?

The CD Key or STEAM Key, is a digital key that will allow us to download the game Mars Horizon in our PC from the Steam game platform. These codes represent the easiest way to buy games online..

Most common FAQs when buying Mars Horizon for PC in digital format:

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

As of 03/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Mars Horizon on PC is €3.26.

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 Mars Horizon 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 Mars Horizon, 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.
