Went there for my first game an thoroughly enjoyed it! It's a fair bit cold down there but you tend to stay warm when running about the place. It may take a while to get your bearings and get an idea of the layout of the place but don't worry if you're clueless at first. Also, take the brightest torch you have because not only is it dark but a bit of a haze also seems to builds up towards the end of the day.
