Surviving the full campaign is not easy, but these tips will help you reach the end. First, always prioritize repairing your barricade if its health drops below half, as a broken defense means an instant jumpscare and game over.

Third, watch the flashlight's vignette effect closely during the night phase to spot the monster's movements early. Finally, save your best upgrades for the ultimate boss fight on the final day, known as The Nightmare.
