Turbine Remix
RR: 7.5
Another interesting remix from Duo; I couldn't find a very impressive screenshot, on my admittedly rather brief first first visit, but the whole layout seemed pretty promising, and the textures were all pretty suitable for a place like this.
          It is all close-quarters stuff here, with fairly narrow passageways, stairwells, and some elevators too, so it would need a fairly large population to give you a proper edge-of-the-seat experience, but it does everything you would want in that direction.  There are quite a few other maps that will do it just as well, of course, but it is always good to have plenty of choice!
          Efficient texturing, and a good basic lay-out, for a good solid average arena.
