I've loaded two server demo files from Ubercon 5. These two demo files were recorded on the server so you can view any person playing.
I recommend watching Aco's goliath match.
You can download the zipped demo files (the two files zipped are 30 MB). Place the files in your UT2004/Demo directory. You must make sure you have the latest UT patch (3355).
I will be bringing all of the demo files to the 7hm lan party, but you can see it from here.
I like the one at about 10:20 in the game when Aco does a long long shock ball launch and dual kill (on Fiendslayer of all people too!)
Check it out by going to the NJLP/Corpus web site storage at: http://www.srygley.us/~njlanparty/uberdemos.zip (the index file will also display it.) :p
