No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $58.4K — a different platform, not this one.

I'm on Observation Duty 8

As an employee of a mysterious organization, your job is to monitor live surveillance camera footage and report other-worldly anomalies using your sharp eyes and good memory. Can you survive the entire night shift, or will you succumb to paranoia? Monitor surveillance cameras across six unique levels, each with their own unnerving \"anomalies\"—supernatural occurrences ranging from subtle environmental shifts to grotesque otherworldly intruders. Report anomalies to \"fix\" them and survive the night. If you can. I'm on Observation Duty is the original viral franchise that ignited a trend in spot-the-difference horror games that are now loved by players worldwide.
