Caverns is an arcade adventure requiring many complex puzzles to be solved before the game can be completed. A high degree of flying skill and accurate shooting are needed, together with patience and dedication if this game is to be completed. The playing area is very large with 15 screens each of which is made up of an area approximately 16 times the size of the monitor. The aim of the game is to penetrate deep into enemy territory and destroy its nerve centre. First you must deactivate the safety devices which are in distant parts of the caves. Along the way you will find ropes to help you pick up items and pipes for re-fueling.
