Dismemberment in SP, the right way!
The 100% way to get dismemberment to work on anyone computer is to edit the .npc files inside the Assets1.pk3. You can use Pakscape to get inside this folder or Winzip. I prefer pakscape. Below is a paste from the Alora.npc.
Change the dismemberprob* to 100 for complete and total carnage.
You can also change what force skills the bot has, yes they will use lightside skills if you give it to them. You can also add saber styles. Making the bots a little more interesting.
Now someone should sticky this one as it has the only right answer. There is no mod and this is the 100% sure fire way to get it to work for the single player. No need to change your launch command or type a bunch of garbage in the console.
Who is the more foolish? The fool or the fool that follows him?
