Sinever First Seal

About The Game

Sinever: The First Seal is a 14 player online co op psychological horror game that can also be played alone.

You and your team enter an abandoned Victorian estate hiding a supernatural prison. Explore its rooms, search for hidden clues, monitor paranormal activity and uncover what the previous owner left behind.

But something inside the house has awakened and every seal you disturb makes it stronger.

• Immersive Psychological Horror: Explore a dark, atmospheric estate filled with disturbing sounds, supernatural encounters, and threats that do not always reveal themselves directly.
• Paranormal Equipment: Use UV flashlights, battery-powered torches, walkie-talkies, sanity pills, and other tools to investigate the estate and survive its dangers.
• Uncover the Seals: Search for seals, symbols, codes, keys, and objects as you piece together the history of the mansion and the entity imprisoned beneath it.
• Manage Your Sanity: Darkness and paranormal encounters gradually damage your sanity. As your mind deteriorates, strange sounds and terrifying events become increasingly difficult to separate from reality.

The house will force your team to separate, take risks, and decide how much you are willing to sacrifice for one another.

• Revive at a Cost: Sacrifice a portion of your own sanity to revive a fallen teammate. Saving someone else may leave you vulnerable to the horrors inside the estate.
• Control Room: Monitor security cameras, observe your teammates, and watch areas they cannot safely enter alone.
• Stay Connected: Use walkie-talkies to coordinate, share discoveries, and warn one another when something begins hunting.
• Think Before You Split Up: Some objectives require players to separate. The person watching the cameras may be the only one who sees the danger approaching.

The deeper you explore, the more the estate reveals about itself, the imprisoned creature held behind the first seal.

• Co-operate: Play alone or with up to four players. Communication, observation, and careful planning are essential to survival.
• Chapter-Driven Horror: Progress through connected chapters, solve the mystery of the estate, and discover the true purpose of the seals.

The house has been waiting.

Will you complete the ritual where the previous owner failed or become part of it?
