New Video Showcases The Dangerous World Of Serum

Experience the dangerous world of Serum

Independent Polish developer Game Island in partnership with publisher Toplitz Productions reveals its latest video presentation for Serum.

The video showcases its fusion of exploration, crafting, and heart-pounding survival against mutated beasts that roam the game world. More details of the player’s ability to craft and concoct potent serums, which can enhance stamina, health, and provide the player with other abilities such as night vision, are also teased.

Survival isn't just a goal - it's an art form. Every encounter requires calculated weapon choices to overcome the challenges presented by the ferocious creatures that inhabit the harsh environment. Serum will feature both single player and co-op gameplay when it arrives next year. Stay tuned for more reveals in the coming weeks.

For more details on the game check out the official Steam page here.


Dive into a thrilling survival adventure where an unknown liquid takes control of your life. Extract Serum to stay alive, battle dangerous creatures, solve puzzles, and uncover clues about past events. Find your way out alone or in a 4-player co-op mode.


Imagine waking up in a world overrun by a mysterious toxic substance with a strange device attached to your arm. Will you gather the courage to explore and survive, or simply wait for your demise? One thing is clear: you need Serum to prolong your life. How you find it is up to you.

Find shelter, search for new technology, craft your equipment and modify weapons to protect yourself, and try to reach places where this precious substance is waiting to be gathered. But be warned: Serum can alter your body in unexpected ways.

Remember: Life is in your hands!
