About Su: Unlocking the 4th Dimension
Su: Unlocking the 4th Dimension is a 2.5D deduction and puzzle game set aboard the Nautilus, a submarine caught in a time vortex. You play as Dr. Pierre, investigating abnormalities throughout the submarine, solving puzzles and exploring its cabins to uncover the vessel’s secrets and find a way to escape.
The Nautilus
In 1866, Dr. Pierre, the Nautilus’s owner, and his seven sailors salvage a compass during a voyage. It gives him a glimpse of his true position in the universe and causes the submarine to sink into a time vortex. Later, Su, a student from a future city, encounters the ancient submarine during an underwater trip. She enters to explore and is pulled by the vortex into an unknown space-time.
Investigate across time
You examine the Nautilus and use observation to solve problems. Interacting with items marked with timestamps lets you penetrate time and find more clues. You also explore time wormholes and use various props to uncover the story’s truth.
