A Protocol Steam Key — also known as a CD Key or digital code — is the official activation code you redeem on Steam and keep in your library permanently. From €5.27 (no fees) at Steam · 6 verified stores, 7 offers in stock · Updated 35min ago.
Final prices with fees and discounts applied
Protocol for PC starts at €5.27 (no fees) at Steam, a Steam key.
Just 6 stores stock it, 7 offers in all, so there is little here to push the price either way.
That puts it 26% under its average of €7.09 since 2019, so today is a better entry point than most days of its life.
That €5.27 (no fees) key is at its usual price: no bargain, no spike.
Worked out from 2,311 daily records of the Steam Key for Protocol across 7 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 €5.27 (no fees) and Steam Gift from €4.72 (€5.47 with fees).
All 7 offers are Global, so the code redeems on any account no matter where it was created.
