Hello Neighbor is a survival horror stealth game developed by Dynamic Pixels and published by tinyBuild. The aim of the game is for the player to successfully sneak into the basement of their neighbor’s house to uncover a secret. The game’s artificial intelligence (AI) modifies the neighbor’s behavior based on the player’s past actions, such as setting traps along paths the player followed in a previous attempt.
In Hello Neighbor, the player finds themselves moving into a new house across the street from a mysterious neighbor who is behaving in a paranoid manner and seems to be keeping a secret in his basement. The player’s task is to break into the neighbor’s home and solve a series of puzzles in order to gather the items needed to unlock and access his basement. As the player explores the neighbor’s house, they must not be spotted by the mysterious neighbor, or they will be chased down, and if the player is not quick enough to hide or escape, will be captured. The player can also stun the neighbor by throwing objects at him for an easier escape. If the player is caught (or suffers a serious injury), they will be sent back to their own house and will have to break in again. Upon starting again, the player must be more careful, as the neighbor will deduce movements from the last attempt to set up traps.
The game is played in a first-person perspective, and the player must aim a very small reticule at the center of the screen at certain objects to interact with them, or use the reticule to throw or use a currently held item (for example, throwing a ball at a window or aiming a crowbar at nails to remove them). Up to four items can be kept in an inventory space, while items of the same kind cannot be stacked together in one slot
