SCROLL TO EXPLORE

01 THE STORY

Some doors should remain closed.

An isolated estate. A supernatural prison. Something inside has awakened.

Search the rooms for clues, symbols, and seals left by the estate's previous owner. Every discovery brings you closer to the truth—and every seal you disturb makes the presence within stronger.

Go in alone or bring your team. Once you cross the threshold, the house decides how far you can go.

02 THE EXPERIENCE

Stay close. Stay alive.

There is more to fear than what you can see. Keep your senses sharp, your equipment ready, and your team within reach.

01 / INVESTIGATE
A candlelit library filled with books and clues

Uncover the seals

Follow symbols, codes, and objects through the estate to piece together the story of the entity beneath it.

02 / ENDURE
A dark corridor stretching into the estate

Question your senses

Darkness and encounters erode your sanity. The deeper you go, the harder it becomes to trust what you hear and see.

03 / SURVIVE TOGETHER
An eerie bedroom with an ornate bed inside the estate

Watch each other's backs

Use cameras, walkie-talkies, and paranormal equipment to coordinate. Some paths will force you apart.

YOUR INVITATION AWAITS

Will you break the first seal?
