A Knock on the Door

A Knock on the Door Online — Original Game Description

A Knock on the Door Online is a multiplayer psychological horror experience where trust is fragile, sound is everything, and every door hides a different truth. You and up to five other players awaken inside a sprawling, shifting building with no memory of how you arrived. The only constant is the knocking—slow, deliberate, and coming from doors that were never there before.

Your group must explore the ever-changing environment, gather clues, and piece together how to escape. But survival requires cooperation… and caution. Not every knock is a threat, and not every voice on the other side belongs to a friend. Some doors hide resources. Some hide paths forward. Others hide things that mimic players, imitate their knocks, and beg to be let in.

Key Features:

• Online Cooperative Horror – Work together to navigate a living, unpredictable map that rearranges itself after each knock.
• Deceptive Social Mechanics – Players can be separated, imitated, or replaced. Trust the wrong person and you may open the door for something else.
• Dynamic Doors System – Any door can become the source of the next knock. You choose whether to open, barricade, investigate, or flee.
• Multiple Endings – Your team’s collective decisions determine whether you escape, uncover the truth, or become part of the house forever.
• Atmospheric Audio – Footsteps behind walls, whispers under floorboards, and unmistakable knocking that grows closer with every mistake.

In A Knock on the Door Online, teamwork is essential—but so is knowing when to leave a door closed.
