Protocol is an atmospheric horror experience focused on exploration, mystery, and uncovering the dark secrets of an abandoned hospital.

You wake up without knowing who you are. Part of your memory is missing, and you have no idea what brought you here.

This hospital was abandoned years ago — left behind and forgotten by humanity.

But there is more to this place than meets the eye.

Hidden beneath the hospital are traces of secret experiments that were never meant to be discovered. As you explore its abandoned corridors, you'll uncover notes, documents, and clues that slowly reveal fragments of what happened here.

Some doors won't open easily. To move forward, you'll need to carefully examine your surroundings and solve simple puzzles along the way.

But the real question is:

Why did you come back?

Because this isn't your first time here.

And after all these years, there is a reason you returned.
