How much does Interstellar Marines for PC cost right now?

Interstellar Marines for PC starts at €1.72 (€2.12 with fees) at HRKGame, a Steam key.

That €1.72 (€2.12 with fees) already includes the Gocdkeys12 coupon, so apply it at checkout or the store will show you a higher price.

Just 6 stores stock it, 8 offers in all, so there is little here to push the price either way.

It is €0.17 away from its all-time low (€1.78, back in April 2025).

Is it worth buying the Steam Key for Interstellar Marines now or waiting?

That €1.72 (€2.12 with fees) key is at its usual price: no bargain, no spike.

  • Those €1.72 (€2.12 with fees) are 30% below what it usually costs, measured on the store price.
  • Only 5 stores sell the Steam Key, and with that little competition the price barely moves.
  • Not counting today, 774 days out of the 2,700 days on record were this cheap or cheaper; the lowest it has ever cost is €1.13.
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 3,095 daily records of the Steam Key for Interstellar Marines across 10 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 Interstellar Marines editions are on sale?

Beyond the standard edition at €1.72 (€2.12 with fees), there is the Special at €5.57 (€6.75 with fees) at Gamivo, €3.85 (€4.63 with fees) more. Check on the store what each one adds before paying the difference.

Can you activate Interstellar Marines in US?

7 of the 8 offers work on US — the Global ones plus the ones issued for your own region.

Interstellar Marines resurrects the old school tactical FPS, offering a unique blend of co-op, role-playing and nonlinear gameplay. Set in a believable future, you take on the role as an elite soldier handpicked to join Project IM, a top secret military program being assembled to protect mankind from all dangers outside our solar system.

Interstellar Marines is inspired by Half-Life, System Shock 2 and Rainbow Six 3: Raven Shield. Our game is all about evolving the FPS recipe with all the inspirations weve assimilated since the birth of the genre. Our goal is an evolutionary leap forward driven by our compulsive interest in science fiction, role-playing, military realism, and respect for first person immersion.

Most common FAQs when buying Interstellar Marines for PC in digital format:

It is a key that will allow you to download the game Interstellar Marines on your PC from official download platforms.
As of 24/10/2026, in United States, the best price we have found in our selection of online stores that include the key for Interstellar Marines on PC is €1.72 (€2.12 with fees).
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 Interstellar Marines 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 Interstellar Marines , 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.
