That's Not My Neighbor

It is 1955. You just started your first day as a security guard at an apartment block — and nothing is what it seems. That's Not My Neighbor is a creepy 2D horror game developed by Nacho Sama - TravConsult Games where your only job is keeping doppelgangers out of the building before they blend in and cause chaos.

These creatures look exactly like real humans. Your eyes and attention to detail are the only tools you have. If you enjoy Scary Games Unblocked, this one will test your nerves in a way most horror games never do.

How to Play That's Not My Neighbor

• Check every visitor's ID before allowing entry

• Match the apartment number on their ID to the correct resident

• Identify doppelgangers attempting to sneak past your checkpoint

• Stay sharp — the impostors get harder to detect as the game progresses

• Do not let a single doppelganger through — one mistake disrupts the entire building

Winning Tips for That's Not My Neighbor Game

• Never rush an ID check — doppelgangers rely on you moving too fast to notice small details

• Always cross-reference the apartment number — a mismatched number is the clearest sign something is wrong

• The later the game goes, the more convincing impostors become — slow down your verification process as difficulty increases

• Treat every visitor as suspicious until their ID proves otherwise — not the other way around

Strategy

The entire challenge of That's Not My Neighbor sits in one habit — checking every detail every single time without developing a false sense of routine. The moment you start approving visitors quickly because the last ten were genuine, a doppelganger walks straight through.

Cross-referencing the apartment number against the ID is your most reliable tool. Real residents have consistent, verifiable details. Doppelgangers almost always crack under a thorough check — so make every verification count.
