You start as a student, expecting a punishment. But all of a sudden you are recruited to the Cosmonaut Squad for some secret experiment. Go through 2-year selection and training process, represented by 14 days (separated by 1-3 months) of vigorous training. But it's not only the training that happens in Zvednyi Gorodok, but that's what you have to explore yourself... Just don't get carried away, or spaceship will fly without you!
Second part of the game (if you manage to get to it) is very different. It is focuesed on simulation and scientific experiments. You will have to perform different tasks, resolve technical failures and trying not to miss designated landing zone.
