A Serum 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 €4.64 (-81%) at Gamivo, 81% below the €24.99 Steam price · 12 verified stores, 27 offers in stock · Updated 25min ago.
Serum for PC starts at €4.64 at Gamivo, a Steam key, which is 81% under the €24.99 it costs on the official store.
We have never recorded it cheaper than this.
That €4.64 already includes the GCDKGamivo coupon, so apply it at checkout or the store will show you a higher price.
With 27 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.
That €4.64 key has never had a real discount yet.
Worked out from 1,661 daily records of the Steam Key for Serum across 12 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 €4.64 and Steam Gift from €30.59.
Beyond the standard edition at €4.64, there is the Ultimate at €8.29 at Cdkeys Com, €3.65 more and the Supporter at €13.86 at Eneba, €9.22 more. Check on the store what each one adds before paying the difference.
23 of the 27 offers work on US — the Global ones plus the ones issued for your own region.
One listing is worth ignoring: the Steam key that GamersGate has at €34.99 is more than 7 times the cheapest offer and is not what this game costs. The number to work from is €4.64 at Gamivo.

What do our users think of Serum for PC Digital?
A futuristic FPS with attractive visuals, solid controls and combat based customization. Travel through neon illuminated labs, tweak load outs to your liking, and unleash grenades and technology-based powers. The gunplay was enough to keep my attention, but there is a noteworthy thin amount of story and while I found it fun, it probably would not hold up too long for action sessions.
