In the year 2018, you are a child inside a very dark house. Nightmares have come to haunt you, as well as robots coming to kill you. How To Play: Hold space to use the flashlight. Survive until 6 AM. Click on the green orb to go to the door. If you hear a robot voice, Lost 6 will come through the door. If your hear a slowish voice at the vent, Lost Gloomy Wunsie will come through the vent. Click on the blue orb to go to the door. If you hear a quickish voice, Lost Gloomsie will come through the door. The Lost Numberblocks from "Hardcore Basics 4" also appear. Shine the flashlight at them to make them go away.
Just kidding there is no hardcore basics four that I know of.
