The Bronze Nightclub: Fighting Spike
After you leave The Bronze and you meet Spike in the alley, you will not be able to defeat him. However, you can make it go quicker by pressing X, A, X while making Buffy turn in either direction at the same time. She will jump up and spin around while kicking Spike, which will knock him out. When he is on the floor, go over to him. Kick and punch him with a stake to lower his power level. A screen will appear and Spike will throw a fireball on the nearby gate. Make sure you do not enter the gate until all flames are extinguished. Then, climb on top of the tires and go up to the top of the building (not the trucks). A vampire will appear. After staking her, run down to the window and you will find another vampire. After staking him, run further down until you find the final vampire. After killing him, you can do two things: either jump down and go through the skylight into a secret room which has an Elixir; or walk carefully around the skylight until you reach a ledge. The game will stop and tell you that you have to shimmy across the pipe above in order to get to the other side to save Willow, and to also get another Health Crystal.
