You have entered into a vast, mysterious and dark tomb. You find yourself at the lowest level of the tomb and must endeavour to find your way through the maze to the top, encountering many hostile beings who are out to get you. You must be brave and fearless, for as you climb the levels, your strength will fade as you are confronted with monsters, acid drops, mummies, rats, skeletons, ghosts and vampires.
Being the intrepid Roland, you are able to jump over the rats to escape them, and shoot the mummies, skeletons and vampires to defend yourself. Shooting at the ghosts will only frighten them away, and there really is no escape from them. Your only means of gaining strength is collecting the vases of Life Elixir, hidden on the tomb floors, or accumulating more bullets and killing more mummies, skeletons and vampires.
