You had two phases to the game both were incredibly short. The first you were a jungle warrior throwing rocks. the second you had moved on to wearing powered armor and were defeating some evil enslaving device.
This would have been cool if there were more to it but it was like a ten minute wash, rinse and repeat affair. You would get screwed on occasion as you could run out of shields in a radio active area and have to get out of the suit only to die to the radiation. That was actually the most interesting the game got as you almost always won.
If i remember right you had to get the shields and guns for the suit then defeat the evil which was pretty easy to do. It sort of reminds me of Metroid in a small way, but that also shows the Commodores flaws. Compared to side scrolling on the consoles it was a total was of time. I do like the Iron Maiden inspired character of the logo though.
