Just for the record, this is NOT a SP dual saber mod - it's MP only. And it isn't really a mod - it just enables cheat mode. From reading the info on it, I presumed there would be a toggle key bind or something for the dual saber. But I couldn't find one anywhere.
I appreciate the guy's attempt and hard work, but personally it wasn't for me. I uninstalled it after trying it for about fifteen minutes.
