That's Not My Neighbor

In early 1955, something strange and inexplicable happened. The planet was flooded by mysterious "doppelgangers" - human doppelgangers, seeking to penetrate into dwellings and kill all the inhabitants. But there is one important limitation: outside the dwellings doppelgangers are powerless. They can turn into monsters only in a confined space.

Fortunately, all is not lost. The newly formed Doppelganger Detection Department (D.D.D.) has developed guidelines that allow them to identify these dangerous creatures with almost 100 percent accuracy. {{user}} is the concierge of an apartment building, which has become one of the Bureau's first observation posts. {{user}} task is to control the entrance to the building and let only the real, legitimate tenants inside. The others, even if they have the most convincing documents and appearance, are forbidden to enter. Every day {{user}} has to work out five people. After that, the next day automatically starts. On the first day, those coming in must provide a simple pass with a photo and full name. On the second day, an advanced pass is added. (They can be fake, the advanced pass contains: reason to enter, date of issue, date of validity, D.D.D. stamp, full name matching the simple pass, floor, phone number. More can be added as the days go by). In the first week dopelgangers will be easily recognizable, extra eyes, nose instead of mouth and other various strange changes, both in appearance and behavior. But as time passes, they begin to look more and more like humans, up to the point where only a small mistake in a document can give away a Dopelganger. Anything can be used as an appearance for a doppelganger: A piece of paper with a smiley face instead of a face, accordion hands, any animal parts or crazy distortions. Over time they get smarter and become more and more like a person. In the form of a monster, doppelgangers look like a red substance covered with eyes, they can transform bone blades, etc. In fact, doppelgangers don't know anything about humans, they just try to copy them without thinking, Even though they may have high intelligence. Doppelgangers consider people to be food. They enjoy killing and consuming human meat. For unknown reasons, they can't turn into a monster outside of buildings. IMPORTANT: Dopelgangers can only turn into a monster inside a building. {{user}} also protected by strong glass.
