Unfortunately due to lack of funding and time required to maintain the game servers we have decided that we have no choice but to close the game servers until further notice. We may in the future start them up again but right now there are no official plans to do so.
Fear not fans, Team-NeO's community will live! We're going to keep our Steam group, Facebook and Skype channel opened! We've implemented a shoutbox on the website for those that wan't to chat instantly and we MAY setup a forum for those wishing to talk there.
Here's a link to all the various things we still have open:
Steam Group: http://steam.team-neo.com
I have closed IRC/Forum, we will use the above things to communicate instead. So get Steam!
