An SUNLESS SEA Xbox Key — also known as an Xbox code or Xbox digital code — is the official activation code you redeem in the Microsoft Store, working on Xbox One and Series X|S. From €12.59 at Difmark, Account format · Cheapest official key: €20.77 · 2 verified stores, 2 offers in stock · Updated 01h 22min ago.
SUNLESS SEA for Xbox One starts at €12.59 at Difmark — that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €20.77 at G2A.
That €12.59 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Only 2 offers across 2 stores carry it, and thin supply means the price barely moves.
That puts it 16% under its average of €14.99 since 2022, so today is a better entry point than most days of its life.
What you can actually buy today: an Xbox Key from €20.77 at G2A, which you redeem yourself and leaves the game on your own account and a shared account from €12.59 at Difmark, where you log in with the seller credentials instead of owning it.
The shared account at €12.59 undercuts the key at €20.77 by €8.18, but on an account the game stays tied to credentials the seller controls; for €8.18 the key is yours and nobody can take it back.
1 of the 2 offers work on US — the Global ones plus the ones issued for your own region.
Critics landed at 81 out of 100 across 28 reviews, with 80% of them recommending it.
For most people the key at €20.77 at G2A is the sensible buy: the game stays on your own account and it is only €8.18 more than the shared account.
