So, way back in June 2004, a top-down vertical shooter TC was released by the name of Xcalon. The archive offered here is basically the same thing, only repacked into another format. From an automatic installer ramming all sorts of files into base UT2004 folder and making an ungodly mess of things (don't you just LOVE to risk a crucial file being overwritten?!) into a launchable mod subfolder and packaged in a zip file. So that you can run it from the Community > Mods listing.
Coz why not.
