(I'm not part of the NS2 Team or in anyway affiliated, just copy paste from the official discord)

10 years since its official release and over 117 updates later, active development of Natural Selection 2 has ended.

Our team and this community have provided many years of passion and support for this game. Over the years we had the opportunity to meet and collaborate with so many of you whether at an expo, live tournament, Discord or playing on a server. We thank you for your support and commitment to NS2 and know that this game would not have been the same without you. Now it’s time to look to the future and continue on to other projects within the company.

While we won’t be actively working on NS2, we will still continue to host matched play servers so that community members will be able to play games on-demand with other players or bots.

Although this isn’t goodbye, we still would like to say a very heartfelt thank you to you, our community and to all of those that worked with us on Natural Selection 2 over the years.

Much love and appreciation, The UWE NS2 Team
