I checked Dead Space, they are all custom images used as background images for headers. So to answer the question, it is mostly done by images, which are implemented through CSS.

I have been experimenting with a similar lay-out myself, but my goal is to achieve such designs through pure CSS. It has some rough edges that have to be ironed out, especially in the navigation-bar, but you can check the pure style at Renegade X Wiki. I can help you with CSS styling if you want to achieve something similar.
