Many years ago there was an arcade game I absolutely loved. It had as an opening sequence an Indiana Jones-esque man and his shapely woman assistant opening a chest that unleashed demons on the world.
The game was isometric, and involved running around shooting and collecting bonus items. The main thing I remember is the ground itself would form into giant golem-like monsters which you would shoot until they fell back into being just dirt.
Does anyone have any clue what game this was?
