Towards the end of Act 3, you'll encounter the 'Shadow Man,' a dark, ethereal entity that represents the Neighbor's guilt and trauma. This entity will chase you through a series of increasingly frantic and claustrophobic environments. There's no direct way to fight the Shadow Man; your only option is to run and hide. The path forward is usually linear, but filled with obstacles and dead ends designed to disorient you.
Your ultimate goal is to reach a final escape point, often a door or a window that leads out of the nightmare. This sequence is a test of your agility and ability to react under pressure. You'll need to sprint, jump, and slide through tight spaces while avoiding the Shadow Man's grasp. Successfully escaping this final chase sequence will trigger the game's ending cutscene, revealing the full story and concluding your journey into the Neighbor's mind. Congratulations on completing Hello Neighbor!
