I broke both legs and was over-encumbered and found myself walking though an abandond factory. it was the immersive point in the game due to the walk speed and raised the tension as I was able to go at a slower pace and creep around; taking in all the details.

Please add a "walk" function to the "CTRL" key (Hold, or Hold/toggle option at same speed as encumbered) as its just begging to be there! :D
