Two hearts. Five heists. One truth worth stealing.
Mara and Theo know how to break into a locked room. Facing the secrets between them is harder. Follow the married thieves through five connected heists in The Fifth Lock, a single-player mystery adventure about trust, a shared past and a job that becomes much more personal than expected.
Search each room for something worth a closer look. Collect objects, keep them in your inventory and figure out how they fit into the puzzle ahead. Repair a mechanism, match a set of symbols or return to a room with the tool you were missing.
You play both characters, taking turns as Mara and Theo lead successive puzzles. Their story unfolds from a Monaco mansion to an Alpine train, a flooded theater in Lisbon, a Madeira observatory and a palazzo in Venice.
