Serum's Demo Arrives at Steam Next Fest

Discover the Enigma of SERUM: Thrive Against the Ticking Clock Amid Devastation and Mutated Foes

Developer Game Island and publisher Toplitz Productions are pleased to reveal that their first person survival adventure game SERUM will have a playable demo in the Steam Next Fest starting Feb 5th.

SERUM is driven by a unique game mechanic: the mysterious elixir (serum) is essential to your survival, a lifeline that has a curing effect of the Blight, a man-made catastrophic event that has left the world in ruin. Discover how this vital liquid can prolong your existence, amplify abilities, and enhance a hand crafted arsenal of weaponry. But beware, time is of the essence, and the clock is ticking. You need to craft different kinds of serum to survive, fight dangerous mutated creatures, solve intriguing puzzles and ultimately escape the dangers you find yourself immersed in... or die trying.

The Next Fest demo will give players their first true hands-on experience of the game as they embark on an exhilarating journey into the heart of darkness. SERUM will challenge players in their quest for survival; their melee and combat skills will be put to the ultimate test as they venture into a world forever changed, resilience becomes paramount.

With a plethora of ungodly mutated creatures to endure and a world of destruction and dereliction to explore in the search for answers, SERUM will encourage the player to survive and adapt in a hostile environment under the pressure of time.

Further details on SERUM can be found on the game's official Steam page, and through its regular devlogs and X (Twitter) diary, revealing more about the world, crafting and macabre dangers that players will encounter.
