I was one of the environment artists on the Season 5 multiplayer map Forbidden, responsible for modeling architectural assets around the level. I established the look for the connected drain system carved into the architecture which was inspired by examples of Incan hydraulic engineering. In addition, I did a modeling pass on a number of the architectural elements in the vista.
Many other people were involved with the areas shown here - Cliff Schuldt has helpfully compiled map credits on LinkedIn.
