First the good news: Doom 4 isn't canceled. Rumors were circulating this past week because someone decided to believe something someone on a message board said was true, but Bethesda has stated otherwise. Yay!
Here's some more good news: A ton of Doom 4 images were accidentally released. These images of Doom 4 came from the portfolio of senior environmental artist, Thao Le. The images were taken down but not before the Internets could get their hands on them.
All Games Beta got their hands on even more supposed Doom 4 images, 170 more to be exact. These new images depict mostly character models and environmental renders. How exciting!
