INTO THE DARK
Biohazard: Siberia is a first person Psychological Horror, where your reality is not really yours. Starting the journey as a normal security officer will soon turn out to be too simple to be true.
This is a game that mixes survival, exploration, and psychological horror. You’ll need to think fast, solve puzzles, and fight your way through an environment that’s out to kill you, all while questioning your own reality.

When a routine security assignment in a secret underground facility turns into a nightmare, your only option is to survive. As Owen Reeves, a new security officer at Ark Nexus, you quickly realize that something is wrong. Experiments have gone out of control, mutants roam free, and reality itself seems to be breaking apart.
Trapped in this crumbling facility, you'll need to explore dark, eerie corridors, scavenge for resources, and outsmart the deadly creatures hunting you. But the deeper you go, the more the truth unravels - and it’s far worse than you imagined.

Survival Horror:
Every moment is tense as you fight to survive. Limited ammo, health, stamina and terrifying enemies, all in mind-bending environments!
Psychological Elements:
Reality is unreliable. As you uncover the secrets of the facility, you’ll start to question everything—including yourself.
Environmental Twists:
As you progress in the game, you can expect various Environments at most unexpected times; One door might lead to a Dense Jungle and other to the middle of the Ocean. All with their own Horrors!
First-Person Exploration:
Navigate claustrophobic hallways, abandoned labs, and hidden chambers. Different Environments that will make you speechless as you Explore for your way out.
Terrifying Mutants:
Face off against twisted, deformed creatures—once human, now monstrous results of dangerous experiments.
Puzzles and Exploration:
Solve environmental puzzles, find key items, and piece together the dark history of Ark Nexus, and take it down!
Atmospheric World:
The facility is a character of its own—rusted metal, flickering lights, and strange noises make every room feel like a threat, with unexpected twists at every Level!
Cutting-Edge Technology
Made in latest iteration of Unreal Engine 5, the game supports Real-Time Illumination, Nanite Rendering and Metahuman technologies to bring the environment to life, and immersion to a maximum! (DLSS, HDR, Path Tracing etc. supported)
