I was responsible for deco pass from beta stage to finish (and support of the location until the release - bugfixing etc.). Deco pass included setting the mood, environment storytelling (supporting the story from the quest “Hydro-puzzle” and story of the world). I worked closely with Quest Designer and Writer to convey the story told in a quest. That also included creating decals of child drawings, blood leaking from the pipes etc.
