Is climb gone? If so will it ever come back? I can't seem to find the server but i tried the test server ip and it doesn't seem to work either. I really liked it and was waiting for it to come out before playing it a bunch. Plus the I couldn't really find anything on the forums about it either.
Climb was put on the backburner temporarily mostly because of trying to work out how to equalize the experience between maps. Some of them require very different settings, some which need to be finetuned. It should make an appearance in the not too distant future though, various other features with it are now working and sorted.
