The objective of the game is to keep water flowing through a network of pipes. Sounds easy maybe but if you count in all the nasty enemies which try to prevent this by blocking the pipes and breaking the system it is more difficult. You are the chief mechanic and you have an assistant by your side who can fix any broken pipes. Your job is to hold off the enemies by shooting enough of them and allowing your assistant to do his job. Great classic arcade action from the times when games were still plain fun.
