Serum: Toxic Survival

About this game

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.

  The Serum Works!

  Hello Survivors, We have some good news for you! First, we sincerely regret our long silence. We understand that this may have been an inconvenience, and we appreciate your patience. There have been some challenges that we have had to navigate, but we are grateful to be able to give you this good news! We are currently working on another update, which will bring you the long-awaited multiplayer, as well as further improvements, especially in terms of quality of life. {STEAM_CLAN_IMAGE}/40377373/8a88742b146860f20641c3e889e6ff3b8d749e69.png {STEAM_CLAN_IMAGE}/40377373/e695e106e582ae4cb602ee5efd8e4b79a0440373.png At this point, it is too early to give you an exact date, but we are currently expecting a release later this year. Keep an eye on the Steam News and our official channels so you don't miss any further information! To set us apart a little from other serums, and also to make it clear that the project is continuing, we have decided to give the game a name that better reflects what Serum is all about: Serum: Toxic Survival. {STEAM_CLAN_IMAGE}/40377373/3a4805b1794e16961168d4dc602e6ebe87d80098.png Thank you for your continued support!
