Jeff the Killer was a fan made game created by Fiona and it was uploaded on Gamejolt. It was a 3d survival horror game.
Jeff the Killer sneaks into a house of an unnamed character. Jeff cuts off the power so the person must use a flashlight to walk around. The person is found by Jeff the Killer inside his house. He must escape the house without being caught by Jeff.
The person gets out the door but is knocked out by Jeff. He wakes up on a chair and Jeff moves in with his knife. The person struggles to escape but cannot. Jeff leans in with the knife and says "GO TO SLEEP" and then the screen goes black and cutting sounds and screaming is heard.
