Michael Taflove, also known as MikeTaf VFX, is an American 3D Animator on YouTube. One of his videos, which looked quite realistic, caused people to think that it's real. But it was just a project for his school.
The video is made on March the 14, 2009. The video starts in a butchers shop, and there's some scary creatures. Five of them were on the floor and just two were on their legs moving. The monsters are copyrighted from a video game titled Silent Hill 2. The monsters which are moving are called Armless, while the ones on the floor are just lying Figures. As well in the video, you will see some long red fluid just moving. It appears that the fluid is not in the game, and that Taflove just added it in the video.
