Why is the Steam Key of Isekai Mining Defense 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 Isekai Mining Defense 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 Isekai Mining Defense?

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 Isekai Mining Defense, 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 Isekai Mining Defense 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.
