Ok, here is one back in the day! I remember seeing this flick along time ago and I am dying to remember the name!Here is what I remember.
1 The title has something with " ...and the four treasures)
2 Our "hero" enters a castle in the beginning
3 at the end(nice skip, but that is what I remember) he puts his hands on two crystals? then his head twists all funky and all this weird shit happens and wipes out the badguys. Now tht I think about it, they get out of the castle by helicopter
4 the final scene is a zoom in on a swamp and some thing snaps at the camera.

Whoever can remember the name of this flick, I will praise your name in all Bboards!
