It was me who made the mods for TheKiller
That particular one simply disables all damage, except to yourself, not just team damage.
Unfortunately i do not wish for these mods to become widespread, as they are in truth extremely unstable, and it is restricted by legal license that i cannot control (form the original LuaMod author), and i would appreciate it if current holders of the files would not distribute them without my consent, thanks.
Also, for it to be any use to you, you must first learn the Lua programming language.
Also, it only works on windows.
If you still wish to pursue the mods, please email me at: firstname.lastname@example.org
