I believe we were very early with creating a deathrun server. Which version it was I don't know. But it was something with "1" at the end. If that was was 1.01 or 1.1 no clue. What I remember however is that Retox Squard created a deathrun server as well in its last weeks of its existance. That was shortly after our server was up. So it was likely May 2011 when we created ours.
However "Blur" was our server given into other hands for a rent. Because I was seriously fed up with dealing with that kids at one point. But that must have been later than the shutdown of Xfire, unless you can find screenshots where it writes "Blur Deathrun" onto them.
