I noticed there are zip files for a Tribes 2 Anarchy Mod for Linux. But the links don't work. Nor do the links work for the Linux update patch.
I've come across a download link for Tribes 2 - Linux here:
http://t2.giantfriend.com/
As of 10/4/2008 the link still works. The archive has just about every custom script installed along with it. But I can't get the Anarchy Mod to work -- if I just copy from a Win32 install to a Linux install. I assume the .dso files aren't compatible for some reason. That or my version is wrong.
