Which digital format of Extinction Day 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 Extinction Day, 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 Extinction Day 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 Extinction Day 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 Extinction Day?

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 Extinction Day, 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 Extinction Day 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.

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.

Everything you need to know to buy Extinction Day 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 Extinction Day for PC in digital format, although there may be others:

-Extinction Day Steam Account: This is an account that contains the game Extinction Day 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.

-Extinction Day Steam Key: It's a cd key that will allow us to activate Extinction Day 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.

-Extinction Day Steam Gift: It's a URL that will activate Extinction Day 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 Extinction Day for PC in Key or digital code format!
