Okay, I know this question is probably horrifically n00bish, but is there a mod for Jedi Academy that lets you switch between Two Lightsabers and a Dual Bladed Lightsaber? I apologize if this question has been asked a zillion times but I haven't seen anything about it in the FAQ's, considering the little Lucas Arts animation in the intro pulls out two light sabers, then connects them into one dual bladed saber, I'm amazed this option wasn't in the actualy game.
To answer your question no not yet. I'm not sure it's possible. I know you can go from single to staff sabers by just changing styles using a staff. I know there are mods that offer the ability to pick up sabers enemies drop. So far that's it, as far as I know. I hope that helps. :D
NPC'S do it sometimes in single player, but i'm not sure if its possible for the player to do it.
I think it's sort of a permanent thing that only works with a saber staff. Basically you add the following lines into a saberstaff's .sab file:
brokenSaber1 modelname brokenSaber2 modelname
And if the game engine calculates that the staff hilt is destroyed, it will switch to those hilts. I'm not sure if it works with the player and if those lines aren't defined then the saberstaff is indestructible... It's actually very rare that you manage to destroy an opponents hilt though...
You don't nescessarily need to add both sabers. Adding one hilt works as well a la Darth Maul and his broken saber...
