About the 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.

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.
