Final prices with fees
How much does Subnautica 2 for PC cost right now?
Subnautica 2 for PC starts at €8.81 (€9.21 with fees) at Difmark, 69% under the €29.99 (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 €23.21 (€25.41 with fees) at Kinguin.
That €8.81 (€9.21 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
With 23 offers across 12 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.

Which Subnautica 2 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 Kinguin costs €14.40 (€16.20 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 8 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 Subnautica 2 in US?
16 of the 23 offers work on US — the Global ones plus the ones issued for your own region.
So, which Subnautica 2 deal should you buy?
For most people the key at €23.21 (€25.41 with fees) at Kinguin is the sensible buy: the game stays on your own account and it is only €14.40 (€16.20 with fees) more than the shared account.
