Here's how you do it:
Open up pak6.pk3 and extract localization.txt to your Main folder. Now in your main foler, there should be a folder called "global", in ther is localization.txt. Now open localization and scroll throught it to find the multiplayer death messages (or whatever else you want to edit) and modify the second entry, so it should look like this:
{ "was perforated by" "was pummped full of lead by" }
And just do that to the rest of the entries that you want to change.
