Life Line is a unique and innovative adventure video game developed by SCE Japan Studio for the Sony Playstation 2. This sci-fi thriller puts players in control of a young lady named Rio, who needs to escape from a space-station hotel invaded by aliens. But, what makes Life Line unique is its voice recognition mechanism. Instead of regular controls, players dictate the actions of Rio through a microphone to solve puzzles or fight aliens. The game combines elements of horror and suspense with puzzle-solving and interactive adventure, making it a one-of-a-kind title in the PS2 library.
