Developer IllFonic has explained why the Xbox Live servers for Nexuiz have shut down. They were controlled and paid for by THQ, and as the publisher no longer exists to pay the bills they got turned off.
Fortunately the PC servers are completely controlled by IllFonic and will continue on. While it's possible they could buy the Xbox 360 servers from THQ, they "cannot justify the cost" right now.
Major Nelson has revealed the content that will be hitting Xbox Live Marketplace for the next two weeks from the 26th June to the 9th July.

The PC beta for THQ's arena-shooter Nexuiz is now live.
A few days ago, GameStop revealed that a new DLC pack, "Lost Archive", was being released for Assassin's Creed: Revelations on the 28th February. The Major Nelson blog has confirmed that UbiSoft's unannounced downloadable content will be coming to Marketplace on that date.
