I have put up, and will keep up, a dedicated server for Retrovirus. Currently there is no way to name it, but of course, it is the level "Moebius". As I have stated at the RV forums, I leave my ship spawned in there when I am available to play. If you come in and see my ship - kill me, and I'll see the red-mist and come play.
The only existing play mode is Peer-to-Peer, so it is likely you will have 120-180ms ping to me playing out of the USA. I'm not sitting on the server at 2ms ping... My ping to you is what you bring with you.
I am very much enjoying RV online: Even though I suck badly. Sergeant Thorne - thanks for coming in and killing me.

See you down in New Zealand!
