stagnant shadow

After a mysterious meteor visits Earth, the images of all living things on Earth have changed dramatically. Every few seconds, "late" a step, every once in a while, an identical virtual shadow will stay in place and slowly disperse. And as the study of this phenomenon slowly unfolds, some new technologies are slowly being applied. At the same time, some terrorists have begun to covet these studies. A research base somewhere is occupied by terrorists, and you are an anti-terrorist, with the blessing of the latest technology, you will clean the entire laboratory alone.
