Ok, since I last posted in this thread I have purchased H&D2, awesome game! Highly recommended.
Also, based on fretnstuff's comments, I finally found Iron Storm sitting in the dusty shelf section at Wat Mart. $10.00 is not much to pay for a great game. Excellent graphics, good story line, tough play even on Easy. There are some places that are extremely difficult until you figure out exactly how to get through them. The enemy, when they are distant from you, are not too intelligent, but when they are after you they are extremely smart.
Thanks for the tip fretnstuff. This is a "Hanger On To!"
