Buy Siege of Centauri Steam Key

Q: Why is the Steam Key of Siege of Centauri 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 Siege of Centauri to your game library. The account format requires more complicated steps and is more prone to errors during activation.

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

Siege of Centauri for PC starts at €2.48 at Eneba, a Steam key, which is 84% under the €15.49 it costs on the official store.

That €2.48 already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.

With 12 offers across 8 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.

It is €0.08 away from its all-time low (€2.40, back in September 2021).

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

That €2.48 key is at its usual price: no bargain, no spike.

Those €2.48 are 4% below what it usually costs, measured on the store price.
8 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
Not counting today, 497 days out of the 1,482 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 3,076 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 €2.48 and Steam Gift from €4.54.

Can you activate Siege of Centauri in US?

All 12 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 gift that G2A has at €16.85 is more than 6 times the cheapest offer and is not what this game costs. The number to work from is €2.48 at Eneba.

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 24/08/2026, 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 €2.48.

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.
