Here you play as buffy and have to find everyone:

Willow: locked in the upper office of the movie theater. she'll get you the key from the window when you go around.

Xander: in a storage garage. find the fuse to open the door and ride the pulley across.

Spike: Willy's Place, the demon bar (of course) chilling by the bar. pick up the pool cue.

Faith: locked in the vault. get the flashlight from the first floor. go back up into the dark room and find the combonation. go down into the basement w/ the elevator and let her out.
