Hello Neighbor had a pretty good concept going. Players had to try and hide from their next door neighbor while investigating their suspicious activity. During E3, tinyBuild revealed a multiplayer expansion for the title meant to become a social horror experience.
Secret Neighbor features online gameplay where a group of players are working together to find kinds and make their way out of a location. However, the twist comes as one or more members of the team is secretly the neighbor and will attempt to thwart their plans. It acts similar to Werewolf where one side is trying to emerge victorious. The Neighbor will be able to use the environment to their advantage while the kids are able to come up with ways of defending themselves.
