If I'm not mistaken, that's a test server for possibly future maps, such as the old PMC servers that were removed (if possible, they should bring them back. They were awesome).
Great idea, but the maps, as said before, were removed for a reason. But, on the bright side, the newer players would possibly play it, but what makes you think they would absolutely love it? Servers are a lot of money, especially the fact that they buy them 25 at a time. I would like it because it reminds me of the good old days back in 2012, but I don't know if it's worth it or not..
