Climb the fence when your character has to, then walk across and climb down or fall off the right side. Do not jump. Then, edge over to the right until the two Williams thugs appear. Go back up the fence, and walk over to the left as far as possible. Then, head back across the fence, and the Williams thugs will be gone. However, along the top of the fighting plane, begin kicking, punching, or using your bat until an invisible, stationary Williams is hit. This "ghost" opponent will not move or attack. Simply keep attacking until your character obtains the maximum seven hearts.
