RULES AND FEATURES
Somewhere deep, deep underground, there was a research dig, then something happened, apparently something collapsed, and there were many researchers buried alive, but still alive, in countless underground caves. Of course, they are not able to solve their own rescue tasks, so you, the commander of the underground flying rescue capsule, have been assigned this task.
Fly underground, find and rescue researchers, shoot at dangerous or seemingly dangerous objects. Passages between caves will only open if you save all the scientists in the current cave. We recommend it as a beautiful, solid and high-quality game!
