The 1980 game created by Roberta Williams that invented the interactive graphic adventure, reborn as 3D horror. Eight friends walk into an abandoned house for what was to be a fun game night. Now you're the one who has to get out alive. Solve the puzzles. Uncover the secrets. Survive the house.

In 1980, Roberta Williams' Mystery House changed video games forever. Now it returns — re-imagined as a beautifully twisted survival-horror set inside the ruins of the house that started it all.

What begins as a nostalgic game night among eight friends spirals into a waking nightmare. As the grandchild of a famous detective, you're invited to "play a game" inside the old estate. But the house is no relic. Its walls breathe with secrets, the rooms are veiled in puzzles, and something in the dark doesn't want you to leave alive.

Its walls keep secrets. Its rooms are built like puzzles. And something inside doesn't want you to leave alive.

As you explore the sprawling mansion, you'll uncover cryptic clues, solve twisted puzzles, and unravel a dark legacy that refuses to stay buried. The deeper you go, the more the truth claws its way out — until it becomes clear this was never a game at all. It's real. And it wants you dead.

You'll need every ounce of wit, courage, and instinct to survive the night, expose what's hidden in these walls, and escape with your life.

Search forgotten rooms, hidden passages, and long-sealed spaces. Every shadow hides a clue. Every drawer could reveal the truth — or something worse.
