About Serum

Unravel the mystery of Serum and survive the fight against time amidst a ruined world of destruction and mutated creatures.

Your life is at stake! The toxic fog obscures the dangers in an apocalyptic world where every second counts. A relentless timer on your arm decides between life and death. Prove your courage, explore the mysterious environment for resources and brew serums for unique abilities. Every dose of serum can make the difference in the fight for survival against mutated enemies. Find shelter in the chaos, search for technology and modify weapons for greater effectiveness. The race against time begins now.





Unravel the mystery of Serum and find your way out while exploring different biomes and their unique characteristics. Find clues about past events and use the new-found wisdom to survive while experiencing beautiful graphics delivered with the power of Unreal Engine 5.


Figure out how to create new tools, traps, and weapons. Gather Serum from animals and plants and expand your safe zone to create a sustainable source of the substance. Prepare wisely for your next excursion to ensure it won’t be your last one.




Take advantage of a unique brewing mechanism that allows you to create various mixtures of Serum. Experiment with dozens of combinations and use them to enhance your abilities. Ensure you’re carrying enough to get you out of a tough spot.




Clash with various creatures using a multitude of weapons: melee, ranged, and throwing including spears, bows and clubs. Use Serum to infuse and modify your weapons and gain the upper hand against mutated abominations that roam the island.




Endure in a hostile environment under the pressure of time. Manage your health, stamina, and beware of Serum side effects.

Everything you need to know to buy Serum for PC at the best price


Assuming we all know what digital versions of games are, which usually come in digital code, key or Steam Key format, let's highlight the 3 most interesting formats for buying Serum for PC in digital format, although there may be others:

-Serum Steam Account: This is an account that contains the game Serum already installed. It's cheaper than the rest, but it may violate certain platform policies, and its activation process is not as straightforward as digital keys.

-Serum Steam Key: It's a cd key that will allow us to activate Serum on our Steam account. It's the most recommended digital version, for its price and ease of activation. If you want to know how to activate this format easily, you can visit our blog with the entire activation process for keys on Steam.

-Serum Steam Gift: It's a URL that will activate Serum on your account and leave everything ready for you to start downloading the game. It's a cheap format with very fast activation, but it has more problems than the other formats.

Our recommendation: Buy Serum for pc in Key or digital code format!

Can I activate the STEAM Key of Serum in my region?


Digital formats of games, and in this case for Serum, often have different activation regions. Currently, at Gocdkeys, we differentiate 4 regions:

Global, which means you can activate that game anywhere in the world.
EU: You can only activate that digital key in regions or countries within the European Union.
US: It's only possible to activate that code in North America.
UK: It's only possible to activate that key in the United Kingdom.
Our recommendation: Buy Serum in your corresponding region or in Global if you prefer not to take risks!

We have 13 years of experience in the digital gaming market and have always resolved any issues our users have had with any store. So, you should trust us, as we will respond to any problems that arise with any of the stores we list. Just contact us and we will help you.

Information about Serum for PC


Serum is an action-adventure game where the fight for survival is a race against the clock in an environment devastated by destruction and plagued by mutated creatures. Face deadly challenges as you enter the dense smog that hides all kinds of dangers. Every second counts, and a relentless stopwatch on your arm reminds you of the constant threat of death.

Explore unique biomes and unlock the secrets of Serum as you venture into this mysterious world. Uncover clues about past events and adapt your survival strategy as you immerse yourself in stunning landscapes, powered by Unreal Engine 5. Collect resources, hunt creatures, and grow plants to ensure your livelihood in this hostile environment.

Experiment with different serum formulas to gain unique abilities and improve your chances of survival. Use an innovative brewing system to create diverse whey blends and customize your strategic approach. Take on the mutated creatures with a variety of weapons, modified with serum to increase their combat effectiveness.

Most common FAQs when buying Serum for PC in digital format:

  • What is the key for Serum on PC?

    It is a key that will allow you to download the game Serum on your PC from official download platforms.

  • What's the best price for buying the key of Serum for PC?

    As of 05/12/2025, in United States, the best price we have found in our selection of online stores that include the key for Serum on PC is €5.54.

  • Why is the Steam Key of Serum safer than the account format? See more

    The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Serum to your game library. The account format requires more complicated steps and is more prone to errors during activation.

  • What issues can arise when activating a Steam Key of Serum? See more

    The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Serum, and they will provide a new key. You can also contact us, and we’ll help you out.

  • How long will I have to wait to receive the Steam Key of Serum after purchasing it from a store? See more

    Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

    Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

    If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.

  • What guarantee do I have that the listed stores are reliable? See more

    At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

    There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

    In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.

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.
