Well, I never saw it before, so I cant say how it changed, but heres what it did. You go into a room and the assistant tells you how the professor is missing and then sees a message on the walls. He reads it, shouldn't have and your all in trouble from the evil guy. A goddess shows up on the wall and leads you deeper into the tunnels. The tour guide finds the trident and eventually gets it to poseiden, who fights the bad guy. He then frees you all through the wall of water. It was okay, nothing great but cute.
