This is a mod that changes the Dark Brotherhood assassin's armor to one that looks more like the one in Oblivion's concept art (in my opinion, of course ;-). None of the original DB armor statistics have been altered. All that was done was replace the relevant meshes and textures, as well as adding the mask to the NPCs inventory. Male and female versions of the armor are included. Also, there is a folder named AltTextures which contains different sets of alternative textures for the cuirass and mask, so that you can choose which kind of replacer you want. Finally, new weapons have been added to replace the Dark brotherhood's arsenal, as well as customizing Dandras Vules (head of the DB in the game) with a unique look: new face, armor, and a special version of Vagabond Angel's Hissyo katana.
