How much does Serious Sam 3 for PC cost right now?

Serious Sam 3 for PC starts at €2.26 at Gamivo, a Steam key.

That €2.26 already includes the GCDKGamivo coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 5 offers from 4 stores — and thin supply keeps prices steady rather than falling.

That puts it 18% under its average of €2.74 since 2017, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Serious Sam 3 now or waiting?

That €2.26 key is at one of its best prices.

  • Those €2.26 are 42% below what it usually costs, measured on the store price.
  • Only 4 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, only 143 days out of the 2,514 days on record were this cheap or cheaper; the lowest it has ever cost is €1.93.
At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 3,137 daily records of the Steam Key for Serious Sam 3 across 8 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Can you activate Serious Sam 3 in US?

All 5 offers are Global, so the code redeems on any account no matter where it was created.

Why is there such an expensive Serious Sam 3 offer?

One listing is worth ignoring: the Steam key that Kinguin has at €11.55 is more than 5 times the cheapest offer and is not what this game costs. The number to work from is €2.26 at Gamivo.

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.

Most common FAQs when buying Serious Sam 3 for PC in digital format:

It is a key that will allow you to download the game Serious Sam 3 on your PC from official download platforms.
As of 23/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Serious Sam 3 on PC is €2.26.
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.
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.
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.
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.

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.
