From what I understand, they still don't have rotations.
Nah, we never did rotations for any of the new sprites for any of the mobile RPG games (Doom RPG, Wolf RPG, or Orcs & Elves); we only did front-facing sprites (and, occasionally, back-facing sprites, depending on the game). The sprites would either need to be used like Wolf 3D bosses, where they don't rotate, or someone would have to draw most of the remaining rotations (which I'm pretty sure hasn't been done by the community yet). The former approach would be fine for the various NPCs, I think, but probably wouldn't be "professional" enough for the free-roaming monsters. Which is too bad, because I always wanted to see a Heretic/Hexen-Orcs & Elves mashup, and Doom II RPG had some nice new hi-res art, including several new actor types.
