If you're getting an error message today (Nov 13) about the "GameSpy master server", it's because Bungie (who now run the master server) are doing some updates on their server.
The updates are taking longer than expected and are causing some performance problems while they are being installed, but the server will be back in full operation as soon as they are completed (no ETA... likely later today/tonight).
We now offer 27 Halo PC and CE servers for your enjoyment! All our servers are listed here. We have also added the new servers to our Xfire list for your convenience.
Among the 11 new PC servers are an Infinity server, a Timberland server and a Zombies server.
And 4 of the PC servers are dedicated to exploring Custom Maps, including some with vehicles and weapons that you've never seen before on Halo PC. Many of these maps have been brought over from Halo CE (and tweaked) by our own PÕQ~Nk_Chick. To explore these new maps please install HAC 2.
Our 4 new CE servers offer more custom maps to supplement our already popular ColdSnap and Ambush servers. Choose from Helix Canyon, Corrupted, Ascension and The Pit. Again, we recommend you install HAC 2 to automatically receive these maps when you join our servers.
All of our servers are subject to change, so check them out soon if you want to experience these particular maps with us!
