I was wondering if you can close the light saber when playing single player on Xbox?
I don't see any reason why you can't. Check the game manual.
On the PC, just pressing the button that switches to the saber turns it off.
I don't think that's possible on the console version.
The console version takes away every good stuff you get on the PC version, thats why it aint worth buying Xbox version. But you can try pressing the same button as how you selected the saber.
