I think I made a mistake on my first character and would like to try a different start. Will a new character also start with all of the pre-order weapons/shields, or an I totally vanilla if I re-roll?
I own the PS3 collector's edition with the additional items provided by the pre order, having said that I have 3 characters and they all had the pre order items available when they were created. I hope this helps you even though I know it's not the PC version.
EDIT: As confirmed by @TonySniper mentioned in the comment below, this does apply to PC as well.
