One of the best NS servers is losing it’s funding and being brought down. That server is "[CoFR]FR31NS – Alien Infest" (Server IP = 22.214.171.124:27015 ) and is one of the most well-run, highest-performing, heavily-admined NS servers out there, and it’s always filled with polite team-players. You may have to wait 20 or more minutes to play, but it’s worth it, it’s that good.
To help these guys out, there is a special change in Constellation this week: any donations received now through Friday, June 20th, will automatically go towards this organization. Just click the Constellation link to donate (you’ll still be a full Constellation member in every way).
