Bethesda has released the first in a series of "behind the scenes" developer videos for Rage.
The first video focuses on id Software's history, and some of the new tech being introduced by the id Tech 5 engine. For example, there's a new Superpixel Editor which allows the devs to tweak the textures so there's never any repetition in the environment. You never feel like you're running down the same series of corridors or same patches of dirt.
Check it out in the video below.
