How can i make a camera rotate like RuneScape?

Ok, first off, yes i have searched the forums for what im looking for and i cant find nothing. ok well if any of you played runescape and know how to make a camera rotate like that i would love to know how to do that. or if any one would like give me a tut. or a .blend showing me what to do. if any one hasnt played it go here… www.runescape.com i would really love the help. thanks.

there is a pic i made in ms paint, showing what i kinda want, i want the camera to move along the the path but i dont know how to do it.

Have a empty parented to the character, and the camera paranted to the empty. Then rotate the empty.
