Which digital format of Mortal Sin 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 Mortal Sin, 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 Mortal Sin 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 Mortal Sin 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 Mortal Sin?

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 Mortal Sin, 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 Mortal Sin 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.

WHAT IS THE Mortal Sin KEY?

It is a digital code, composed of a series of numbers and letters, that you can redeem on official platforms (such as Steam) to obtain an original copy of your video game in digital format.

TOP 3 REASONS TO BUY Mortal Sin FOR PC

1- Mortal Sin is a roguelike-style action game set in a dark fantasy world.

2- Survive a terrifying experience where you will face nightmarish creatures with clear references to folklore stories.

3- Move through a scene of suffocating cobblestone corridors distributed in a labyrinthine shape.

Mortal Sin INFORMATION

Gender

Although it is a roguelike and has great replayability, its aesthetics and gameplay move away from conventional games of this genre to offer a different and fresh vision.

Argument

Play as a fighter who enters a labyrinth full of creatures from hell. A hellish world where nightmares come to life and will force you to fight with all your might to find a way out of the labyrinth in which you are trapped.

Characteristics

- Enjoy a real-time combat system with very intuitive controls that will allow you to learn to play in a short time, but with enough depth so that you face a real challenge if you want to master them.

- You will have 15 warrior classes that you can customize with 30 different weapons and all kinds of bonuses that you will have to combine depending on what you find during the game.

- Go through more than 45 levels that change routes with each new game to offer a unique experience each time. Find your ideal combination of weapons to overcome each challenge depending on the characteristics of the new scenario.

WHAT WILL YOU FIND IN GOCDKEYS?

You will find a price comparison in different stores of the standard PC edition of the video game Mortal Sin in Steam Key format, to make it easier for you to find the cheapest price or the best offer.
