Return to Mysterious Island 2, the sequel to adventure game Return to Mysterious Island released in 2005, and inspired from Jules Verne’s novel The Mysterious Island, offers the player an experience comparable to that of Robinson Crusoe or one of Verne's characters. 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. Return to Mysterious Island 2 begins with the crash of the helicopter that came to rescue Mina. She survived but is once again trapped on the island. All of a sudden, under her very eyes, an unknown disease afflicts the plants first, then the animal life. Mina explores the island to locate the infection source. She searches Captain Nemo's base in vain, then the ruins of an unknown civilization, and finally understands that it is outside pollution that threatens the island. The only way to save this natural wonder is to turn the shield back on. But if Mina makes this decision, she gives up -as Captain Nemo did before her- the idea of returning to civilization…
