Buying at Kinguin saves you 81% compared to the official store

Most users have had positive experiences buying at Kinguin4.6(118.9k) which has an offer with a price of 2.09€

How much does ZERO PROTOCOL for PC cost right now?

ZERO PROTOCOL for PC starts at €2.09 at Kinguin, a Steam key, which is 81% under the €11.10 it costs on the official store.

That €2.09 already includes the AUGGOC10 coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 6 offers from 5 stores — and thin supply keeps prices steady rather than falling.

Can you activate it in your region?

5 of the 6 offers work on US — the Global ones plus the ones issued for your own region.

Why is one listing so expensive?

One listing is worth ignoring: the Steam key that Steam has at €11.10 is more than 5 times the cheapest offer and is not what this game costs. The number to work from is €2.09 at Kinguin.

So, which ZERO PROTOCOL deal should you buy?

€2.09 at Kinguin is the one to take.

Information about ZERO PROTOCOL for PC


Enter the enigmatic world of the IAS Antarctic Research Complex, where your survival becomes a constant struggle in this first-person sci-fi thriller. Face challenges that require wits and skill: you'll need to select passwords to access doors, search for keycards for terminals, repair broken devices, and combine items. This game won't make things easy for you, so be prepared to think critically.

Even though you have a gun, the feeling of safety is short-lived. The enemies lurking in this environment are lethal, and not all of them can be eliminated. The graphics evoke the aesthetics of classic 3D titles such as Zero Tolerance, System Shock, and Half-Life, creating a dense and oppressive environment that reinforces the sense of danger. Carefully crafted sound effects add an extra layer of tension to the experience.

The balance between clarity and madness is key in this game. Every decision you make, whether conscious or impulsive, will have repercussions that will lead you down different paths. As you explore, you'll need to keep an eye out for details and clues that can help you unravel the complex's secrets.

With each step, the player will be forced to adapt and react to a hostile environment. Combining elements and strategically using resources will be essential to progressing through the story. Immersion in this eerie world feels palpable, making every action count in your search for answers.

Most common FAQs when buying ZERO PROTOCOL for PC in digital format:

It is a key that will allow you to download the game ZERO PROTOCOL on your PC from official download platforms.
As of 02/08/2026, in United States, the best price we have found in our selection of online stores that include the key for ZERO PROTOCOL on PC is €2.09.
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 ZERO PROTOCOL 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 ZERO PROTOCOL, 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.
