IKO 39 is an adventure and sci-fi detective game in which the user will feel the most alone. And it does not relax, but rather strains. It is impossible to predict what awaits the protagonist around the corner, which is the main difficulty. Of the weapons in the hands of only an adjustable wrench, which does not add optimism at all. Actions take place in the distant future, where people have already begun to colonize the planets, and the Earth has become the main center of communication and transport hub between systems and galaxies. One day, the 39th colony stopped communicating. And then an experienced engineer Sim Kazer was sent there.
