Which digital format of Book of Demons 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 Book of Demons, 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 Book of Demons 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 Book of Demons 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 Book of Demons?

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 Book of Demons, 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 Book of Demons 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.

Attention: Book of Demons is a game in digital key or Steam key format (although it may also be available in other versions such as Steam Gift), depending on which online store you buy. Depending on the format it must be activated in one way or another. Remember also that they may have regional blocking, so pay attention to this information and check each of the stores.

Book of Demons is a hybrid Hack&Slash, as it also combines elements of card games. A Deckbuilding in which we decide our way of playing with selected cards, and which represent skills, weapons,... Prepare to face the legions of demons and save your kingdom from this threat.

All the action takes place in the dungeons, and these in turn are generated by procedures, so we will rarely find two equal dungeons. More than 70 different types of monsters, with different features and custom mechanics. The most interesting novelty, apart from its attractive and graceful visual style, is that weapons, skills, magic, etc. are expressed with cards. Each of the cards has different rarities that will increase the power of these actions in combat. The treasures that we will discover will contain great amount of new cards that we will be able to incorporate to our collection.

Steam Key activation method: This product is a digital version or cd key, which means that you simply have to access your Steam account and enter the cd key, or key, that you will receive by email in "Assign new product" located in your "Library" on the bottom left. The process is very simple and safe, and in a few steps, you can access your library of Steam games to play Book of Demons without any limit.
