Which digital format of Serious Sam 3 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 Serious Sam 3 , 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 Serious Sam 3 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 Serious Sam 3 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 Serious Sam 3 ?

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 Serious Sam 3 , 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 Serious Sam 3 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.

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.

I'm desperate: They don't send me the game, the store ignores me. I think I've lost my money.

Serious Sam 3: BFE is a glorious throwback to the golden age of first-person shooters where men were men, cover was for amateurs and pulling the trigger made things go boom. Serving as a prequel to the original indie sensation, Serious Sam: The First Encounter, Serious Sam 3 takes place during the Earth’s final struggle against Mental’s invading legions of beasts and mercenaries. Set against the collapsing temples of an ancient civilization and the crumbling cities of 22nd century Egypt, Serious Sam 3 is an exhilarating fusion of classic twitch shooters and modern gameplay features.

Intense top notch old school shooter. This game offers no cover but what it does offer you is a variety of weapons to mow down a screen full of aliens.
