You'll want to google StealthPatch to use the patch (it's what I use.)
I just got an idea- if we don't have the original comments, we could just play with the code a bit, see what happens, and add our own comments to make modding less hard. It's kind of redundant for every single person to research the same piece of code.

EDIT: I hope that if this gets done, everyone upgrades. Make sure that nobody with an earlier version would be able to get into a new server at all, because then they could still use the Laser Shield.
