Taking place on Halloween, a lone child trick-or-treating comes across the TRAFFIC home. They knock on the door and a familiar face answers. They offer you some candy; all you need to do is step inside the house and take some. Think you're brave enough?
This event will have multiple endings, new mechanics, scares, music, and replayability. It will be a free and permanent addition to the game that can be accessed at any time, even after Halloween is over.
It'll be crazy, it'll be stupid, it'll be a lot of fun.
