The Pre-Alpha & Alpha 1 of Hello Neighbor is a completely free "early demo" of the Stealth Horror Game. It features a very basic house and basic gameplay elements. It's been developed as a proof-of-concept that it is indeed possible to make interesting gameplay with the premise of breaking into your neighbor's house, and having the AI learn from your moves.
Expect to get glitches, crashes, and unfinished features, but also a good bit of fun.
Hello Neighbor is a stealth horror game about sneaking into your neighbor's house to figure out what horrible secrets he's hiding in the basement. You play against an advanced AI that learns from your every move. Really enjoying climbing through that backyard window? Expect a bear trap there. Sneaking through the front door? There'll be cameras there soon. Trying to escape? The Neighbor will find a shortcut and catch you.
