About this game

Enter… if you dare.

Project 43B is a psychological survival horror where every step could be your last.
You wake up trapped inside a dark house, filled with laser traps, puzzles, secrets, and restricted areas, buried deep within an experiment gone wrong.
There is no easy exit. No help. And you’re not alone.

A grotesque entity, born from a failed experiment, lurks in the shadows.
It follows sound. Reacts to light.
And it wants you.

Breathe slowly. Move silently.
It listens. It smells. It hunts.
That… is 43B.

Game Features:

• Stealth + Survival: Move carefully and avoid direct confrontation.
• Practice Mode: Explore the map without the creature. Learn. Plan. Survive.
• Critical Mode: Total darkness, only a flashlight, and your nerves ready to snap.
• Atmospheric Terror: No cheap jumpscares. Here, fear is real… breathing down your neck.
• Exploration + Puzzles: Find clues, unlock paths, and escape… if you can.

Designed for players who enjoy psychological horror, stealth, tight spaces, and the constant feeling of being observed.
Every hallway hides a story. Every door could be salvation… or your end.

Will you survive Project 43B?
There’s only one way to find out…
