As you know, NS2 launched in beta several months ago and has suffered from intermittent stability issues, mostly relating to the growing in-game economy, diplomatic networks and Alliance complexities. On July 1st, we are going to be taking the game down in order to perform substantial work on its architecture and features. This will not be a simple process and we are not able to give a definite timeline for when the game will return.
To ensure that players do not lose out because of this interruption, we will be turning off new registrations and payment options this week.
We regret having to take such extreme action but unfortunately, the underlying design of the game has several major flaws which must be addressed otherwise it will become irreversibly broken. As soon as we have new information, you'll be informed. In the meantime, perhaps we could interest you in Utopia Kingdoms? It's a game which is heavily based on the management of a kingdom and its associated economy and military. Certainly not a carbon copy of NS2 but hopefully something to get involved with until NS2 returns. This is a link just for NS2 players: here
