How much does ZERO Sievert for PC cost right now?
ZERO Sievert for PC starts at €7.80 (€8.15 with fees) at Difmark, 59% under the €19.99 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €8.46 (€8.85 with fees) at Gameboost.
That €7.80 (€8.15 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
With 24 offers across 15 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.
That puts it 17% under its average of €11.75 since 2022, so today is a better entry point than most days of its life.

Worked out from 2,840 daily records of the Steam Key for ZERO Sievert across 20 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 ZERO Sievert format should you buy?
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Gameboost costs €0.66 (€0.70 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 5 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate ZERO Sievert in US?
18 of the 24 offers work on US — the Global ones plus the ones issued for your own region.
