Help me out here. Back in the late 80s, the local arcade had a game which I have yet to find in MAME and no name rings a bell either.
It was a sidescrolling game where your knight type person went left to right and fought enemies. The thing that has always stuck out in my mind is that you could angle your shield to block (high, mid, low) and as you get hit, you'd lose different pieces of armor.
That's all I got. Vague, but you guys are like psychics so I'm not worried.
