Which digital format of Marathon 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 Marathon, 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 Marathon 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 Marathon 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 Marathon?

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 Marathon, 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 Marathon 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.

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 Marathon

From the creators of Halo and Destiny

Scavenge the lost colony of Tau Ceti IV in Bungie’s team-based FPS extraction shooter. Choose your Runner and work together in crews of three as you battle rival teams and hostile security forces for weapons and upgrades. Survive and your loot is yours to keep for future runs on Tau Ceti—or if you’re brave enough, a journey to the derelict Marathon ship that hangs above.

Become a Runner

Choose from a roster of cybernetic mercenaries with unique abilities. Customize your playstyle with the weapons, implants, and equipment you collect on your runs. Every match is a chance to experiment, buildcraft, and come back stronger.

Welcome to Tau Ceti IV

What once was a thriving colony is now a battleground for rival factions competing for power and fortune, hiring Runners to track down weapons, valuables, and the edge they need to win.

Fun and competitive at all skill levels

Bungie’s best-in-class first person gunplay makes playing at every skill level satisfying. With multiple maps to choose from, you can sharpen your skills in starter areas, then challenge yourself in high-stakes zones and Ranked mode in season one.

Committed to fair play

Cheaters don’t stop, so neither do we. We’ll continue to invest in robust anti-cheat and dedicated server support to keep your games competitive.

Everything you need to know to buy Marathon for PC at the best price

Assuming we all know what digital versions of games are, which usually come in digital code, key or Steam Key format, let's highlight the 3 most interesting formats for buying Marathon for PC in digital format, although there may be others:

-Marathon Steam Account: This is an account that contains the game Marathon already installed. It's cheaper than the rest, but it may violate certain platform policies, and its activation process is not as straightforward as digital keys.

-Marathon Steam Key: It's a cd key that will allow us to activate Marathon on our Steam account. It's the most recommended digital version, for its price and ease of activation. If you want to know how to activate this format easily, you can visit our blog with the entire activation process for keys on Steam.

-Marathon Steam Gift: It's a URL that will activate Marathon on your account and leave everything ready for you to start downloading the game. It's a cheap format with very fast activation, but it has more problems than the other formats.

Our recommendation: Buy Marathon for PC in Key or digital code format!

Can I activate the STEAM Key of Marathon in my region?

Digital formats of games, and in this case for Marathon, often have different activation regions. Currently, at Gocdkeys, we differentiate 4 regions:

Global: Which means you can activate that game anywhere in the world.

EU: You can only activate that digital key in regions or countries within the European Union.

US: It's only possible to activate that code in North America.

UK: It's only possible to activate that key in the United Kingdom.

Our recommendation: Buy Marathon in your corresponding region or in Global if you prefer not to take risks!
