do u know how to get harley on your party for the entire game?
During the course of the game, she willingly leaves the
party for the rest of the game. This can cause some strife if you want to use
her on a NG+, because she won't be carried over. However, all's not lost! To
transfer her over (using the ChronoCross method at Temporal Vortex), you MUST
beat the final boss while she's still in the party. This can only be done on
a NG+, meaning she can't be transferred over until the THIRD playthrough. It
sucks for Harle fans, but that's how it goes.
