[PC][2020-2025]Mimic walks among you and your friends but no one knows

I saw a video of this game a while back—it had graphics similar to DayZ or Phasmophobia. Four friends were playing together, all wearing hazmat suits. They were crouched behind a science-looking desk, lined up and staring at a door. The room looked like a dark chemistry lab, maybe in a school, and they were using flashlights to see.

Suddenly, the friend closest to the door dies abruptly, and the group starts laughing. The person recording looks back at the other two friends—one of them isn’t moving much, but he doesn’t think anything of it. He looks away for a second, and when he looks back, the friend at the back of the line is standing upright, head tilted, staring at them. It’s not actually their friend. They panic and run, and the video cuts off.
