For the uninitiated, tinyBuild Games' Hello Neighbor is a game about breaking into your terrifying neighbor's home in an effort to see what dark secrets he holds in his basement. The game already contains a smart AI that will learn from a player's previous break-in attempts and adapts to catch them in the act, but a new Sonic the Hedgehog mod for the game makes the home invasion substantially harder, as well as more horrifying.

Not only does the mod make Hello Neighbor's creepy antagonist look like Sonic, but he also gains a significant increase in speed. Because of this, even getting spotted from far away will result in the Sonic/Neighbor mashup catching up with the player almost instantly. The blue blur himself is also capable of being at any part of his home in an instant, making avoiding detection just that much more difficult.

On occasion, Sonic the Neighbor will also visit the protagonist in their own home across the street. As seen at the end of the mod showcase above, the creepy hedgehog enemy has no problem with some home invasion of his own, but he feels no need to be subtle about it. Now that Hello Neighbor has finally launched for PC and Xbox One players, it's likely that we'll see an increase in fan mods over the coming months, with results varying from minor game improvements to terrifying nightmare fuel.

Although gameplay videos often showcase the initial break-in phase of the game, Hello Neighbor has a lot more content to explore once users make it into the basement, with creepy robots and a sinister-looking classroom sure to hold some secrets for users talented enough to discover them. Of course, the threat of the neighbor doesn't end once players arrive in the area, and trailers indicate that gamers will be endlessly pursued as they attempt to uncover the intelligent AI's secrets.

The game has long been one of our most anticipated horror games and, now that it has finally released, we're eager to explore what the title has to offer. But we'll probably stay well clear of the Sonic the Hedgehog mod.

Hello Neighbor is out now for PC and Xbox One.
