The year is 2029. The date is Christmas Eve. At the grand opening of the Japan Space Station Hotel, a horde of creatures bursts into the hotel and they start killing everyone. You manage to escape, but you are trapped inside a security room with no chance of getting out. Your only hope lies in Rio, a lone woman, whom you guide by talking to her. Guide her well, and she may be able to rescue you. Rely on her, for she is your one and only life line. (mobygames)
