Only 1 or 2 active servers with pings below 100 nearby. Usually playable late night during the week, or on the weekend. I don't understand why they separated Combat from the original release. I believe that had a detrimental effect on the community; preventing people who were sitting on the fence, from giving it a try, as it was (my understanding) the most popular gameplay mode from the original Half-Life mod.
Bit of a shame, I am always hopeful the original development team retaking the reins of development will breathe new life into it.
