Neighbor's Doppelganger 2: Nightmare Mode

A security guard screens residents at the window of a nightmare-filled building. In Neighbor's Doppelganger 2: Nightmare Mode, routine checks become a test of who belongs inside. Visitors may be ordinary neighbors or dangerous doubles that copy a resident's appearance. Compare what each person says about themselves and why they want access with the whitelist data before choosing what to do. Letting a double pass breaches the building. Rejecting a real resident also breaks protocol.

How to play?

When someone steps up to the window, information cards appear below that person with personal details and the request for access. Select the documents and review them. Then check the whitelist on the right side of the screen and match the visitor's details against the listed data. Watch for mismatched information or suspicious details. Press the green button on the right for a real neighbor. Press the red button on the left to eliminate an anomaly. Mixing up those choices can fail the run. Review each resident on their own, check the request carefully, then choose the correct button. Nightmare Mode requires full attention through the entire inspection, since each decision decides who gets inside the building.
