Vida was Conada Soft 's first major project created in DIV. It is set on Mars and was originally going to have a final chapter on Earth, but it was scrapped.
It all begins when a space research team finds traces of life in a meteorite that broke off from Mars and reached Earth thousands of years ago. This, along with other evidence, raises the possibility of launching a manned mission to Mars in search of signs of life. So each agency chooses its best men to launch the first manned mission to the red planet.
