A Windows demo has been released by Microids, for Return to Mysterious Island 2, to show some playable gameplay from their sequel to Jules Verne-inspired 2005 adventure game. Here is the download link. Word is:

"But in this new installment, survival is not all! The player will also have to save the island from an environmental disaster. The scenario enhances ecological issues that were already shared by Jules Verne and that no one ever questions today."
