ZERO PROTOCOL is a premium first-person sci-fi action game where players experience the nostalgia of classic 3D games while uncovering the dark secrets of a remote Antarctic research station. Players can solve puzzles, explore non-linear storylines, and face monstrous creatures that lurk in the shadows as they fight for survival.

Explore a deadly research facility

ZERO PROTOCOL delivers an atmospheric experience inspired by System Shock, Zero Tolerance, and Half-Life. You’ll unlock doors, repair equipment, and search for access cards, using your wits to navigate this hostile environment. The game emphasizes exploration over guidance, encouraging players to think critically as they work their way through challenging puzzles and objectives.

However, the non-linear structure and limited guidance may be a double-edged sword—while they offer freedom that lets players make choices affecting multiple endings, they may also frustrate those who prefer a clearer path. The game leaves much to the player’s intuition, requiring patience and perseverance to uncover all its secrets.

For fans of sci-fi horror

ZERO PROTOCOL offers an intense and immersive experience that will appeal to fans of vintage sci-fi horror games. While the non-linear structure and minimal guidance provide depth for those who enjoy piecing together clues, it may deter players looking for a more straightforward experience.
