"No, I'm Not a Human"

Main premise: The sun has exploded (or something catastrophic has happened to the world).

Now there are "Visitors" (imposters/doppelgangers) emerging from the Underground and posing as humans.

You are locked in your house, and your only mission is: Never leave.

Close all doors and windows.

Only let real humans in.

Identify and eliminate the Visitors who try to enter.

If you make a mistake and let an imposter in… things get very bad.
