Hello Neighbor 3 Expands to Open World with Autonomous AI
The series' signature learning AI is being rebuilt as a town-wide autonomous simulation, shifting the cat-and-mouse premise from one mansion to a systemic open world where the player's accumulated knowledge, not the map, expands the play area.

Series creator Nikita Koreshnikov detailed Hello Neighbor 3 at gamescom 2026. The sequel moves the stealth action from Mr. Peterson's mansion to the open world town of Ravenbrook, where a time loop resets the world and the player keeps the knowledge. The town runs on GOAP-based autonomous AI: 8 to 9 NPCs with their own motives, relationships, and off-screen simulations. The game is in alpha, with free playtests running on Steam.
Koreshnikov said the player tracks a corporate employee who vanished in Ravenbrook, and the story is self-contained for newcomers. Residents treat the player as an outsider working for the corporation that threatens their way of life; a boy named Isaac is the only one who stays friendly, watching out of curiosity. The Vandals, a delinquent group in road signs and safety cones, attack residents and the player alike, breaking into buildings and throwing people from roofs.
The game runs on Unreal Engine 5 with Lumen lighting, set in early spring. Development is in alpha with a core team of about 16 in-house staff, after the first game's 4 to 5 person team and the outsourced second entry.
