Mushroomers tend to stick to one side of the tank by the ends of their flagellum if left alone. After being eaten by a nautilus, it overruns its predator and consumes it from the inside out. As a Mushroomer, the Seaman is essentially a parasite. The Seaman lacks a face and any verbal means of communication. The Seaman begins its first days of life as a Mushroomer, a form which consists of a well-developed optic organ and a flagellum. Over the course of the game, the player is required to evolve their Seaman to different stages in its life cycle, eventually transforming into a frog-like creature outlined on the disc's cover. The player is also provided with multiple Seamen for breeding and interaction purposes. Through various buttons on the Dreamcast controller, the player controls all the machinery and physical contact with the mysterious creature. Īt the beginning of the game, the player is provided with an unhatched Seaman egg and develops and interacts with it through various stages of development. When he asks what the player's birthday is (and the player responds via the microphone input), the Seaman will share significant events that happened on that date.Īlthough the Seaman becomes fairly domesticated, it does not stop insulting the player or making less-than-friendly remarks. A portion of the Seaman's knowledge is random trivia. The mechanic operates in real time, so the player is required to check on the Seaman every real-time day or he could die. The player's goal is to feed and care for the Seaman while providing him with the company that he needs. Seaman is considered a unique video game because it contains limited action. Seaman is played using voice commands and came bundled with the official Dreamcast microphone.
