I can see why you'd say Scramble, horizontal scroller in a cave-type place. But this little number was a home console exclusive, never in an arcade. It only appeared on one console, and the company that made it didn't make it through the big videogame shake-up of '83-'84.
oops..its not scramble its laser gates.
