Beyond Citadel for PC starts at €13.48 at Driffle, a Steam key, which is 9% under the €14.79 it costs on the official store.
That €13.48 already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 5 offers from 5 stores — and thin supply keeps prices steady rather than falling.
That puts it 9% under its average of €14.79 since 2025, so today is a better entry point than most days of its life.
That €13.48 key is expensive for what it usually costs.
Worked out from 525 daily records of the Steam Key for Beyond Citadel across 5 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.
By format: Steam Key from €13.48 and Steam Gift from €16.86.
All 5 offers are Global, so the code redeems on any account no matter where it was created.
