How much does Siege of Centauri for PC cost right now?

Siege of Centauri for PC starts at €2.57 at Driffle, a Steam key, which is 34% under the €3.87 it costs on the official store.

That €2.57 already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.

The listing shows 14 offers from 10 stores, though only 13 can be bought at this moment — the price above comes from those.

That puts it 13% under its average of €2.94 since 2019, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Siege of Centauri now or waiting?

That €2.57 key is at its usual price: no bargain, no spike.

  • Those €2.57 are essentially what it usually costs.
  • 9 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
  • Not counting today, 618 days out of the 1,462 days on record were this cheap or cheaper; the lowest it has ever cost is €1.04.
It is not a bad price, but it is not this Steam Key's floor either. If you are in no rush, we will tell you the day it drops.

Worked out from 2,882 daily records of the Steam Key for Siege of Centauri across 11 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.

Which Siege of Centauri format should you buy?

By format: Steam Key from €2.57 and Steam Gift from €5.63.

Can you activate Siege of Centauri in US?

All 14 offers redeem on US, so region is not something you have to check on this one.

Why is there such an expensive Siege of Centauri offer?

One listing is worth ignoring: the Steam key that Greenmangaming has at €15.49 is more than 6 times the cheapest offer and is not what this game costs. The number to work from is €2.57 at Driffle.

So, which Siege of Centauri deal should you buy?

Get it now: the cheapest key is at Driffle for €2.57 and the game stays on your own account.

The lowest we have ever seen is €1.04, so waiting is unlikely to give you much more than you already have today.

Siege of Centauri is only available in digital version and can be purchased directly from the Steam shop, or through digital keys in other online shops. It can be available in cd key format or in "Steam Gift" format so pay attention to the format you are going to buy in each of the stores.


Siege of Centauri is a Tower Defense game, in which we will fight for the survival of the Earth in the face of an alien invasion. We'll put ourselves in charge of interplanetary defense with an enormous amount of resources and state-of-the-art weaponry. Thousands of alien machines are attacking our domains and only we, with our arsenal of weapons, will be able to stop them.


We will have to choose wisely the positions in which to place our defenses, since certain enemies will be affected to a lesser or greater extent by our weapons. Siege of Centauri combines the best elements of the classic Tower Defense games with the strategic depth we've seen in other titles like Sins of a Solar Empire: Rebellion and Ashes of the Singularity.

Most common FAQs when buying Siege of Centauri for PC in digital format:

It is a key that will allow you to download the game Siege of Centauri on your PC from official download platforms.
As of 04/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Siege of Centauri on PC is €2.57.
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 Siege of Centauri 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 Siege of Centauri, 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.
