With the help of this community (user test1) I was able to get a lua script working which enables the special kill animations on cloakers and tasers with all characters and all weapons. Decided to throw it together and submit it, that way others who read the thread don't have to manually create the .lua and mod.txt files.

This is the first thing I uploaded here, so I'm unsure about the rules. I've written myself in as the author, because I'm putting it up, and gave special thanks to test1 in the mod description. If that's not how it should be done, I'll change it. I take no credit for the code, all I did was write up the mod.txt file.

TL;DR dismember cloakers and tasers with any weapon or character
