Here's how the game is described: "The Ondine, the biggest and most luxurious cruise ship ever built, departed on her maiden voyage long ago. But her enormous pools, ornate casinos and grand ballroom were never seen again. Now the Trident Corporation has sent you to locate the ship and rescue its remains. During this dangerous mission, you lose all forms of contact and collide with the Ondine.

"Very soon you discover that the disappearance has something to do with the odd green fumes that cover the decks and rooms of the vessel as well as the Insanes, its invaders. Moreover, through a mysterious mirror you move to a very odd place, where everything happening around you is somehow occurring in two parallel worlds!

"Which world is real, and which one is just a hallucination? Are the people you meet really alive … or are they ghosts? Search every deck of the gigantic ship for clues, solve challenging puzzles and master entertaining mini-games on your way to the breathtaking truth!
