Description Secret Neighbor: Hello Neighbor Multiplayer:
Secret Neighbor is a multiplayer Social Horror game set in the Hello Neighbor universe. Explore the Hello Neighbor house with your friends, but beware - one of you is the Neighbor in disguise. Use teamwork and rescue your friend from the basement, or mess with everyone’s heads as the Neighbor!
Your group has one goal - sneak around the house, collecting the keys in order to unlock the basement door. The only problem is - one of you is the Neighbor, a traitor in disguise!
Cooperate with your teammates, stay together or tactically split up, use your perks and abilities, and drop those basement door locks one by one.
