Woof3d is a mod for registered Wolfenstein, made by SK Louie. It was released on February 22, 2018.
The mod only took a few hours to make and was made more as a showcase for fun rather than a proper mod. A number of dogs have been added to E1L1, and rather than shooting the dogs, the protagonist is meant to pet them until they fall asleep.
A handful of new graphics were made for the project. Registered Wolfenstein v1.1 is used, making it only available in DOS.
