I wouldn't hesitate if I knew what the controls were and what all the power ups did, but I haven't got a clue. Robocod is one of my all time favourite Amiga games so I jumped at the chance to play the sequel - I didn't even know it existed until about 6 months ago, but I just couldn't get to grips with it at all. I posted a question about it here at the time, but either no-one was familiar with it or they couldn't work it out. I'll search Google and see what I can come up with.
Edit: this link - http://www.baetzler.de/amiga/jamespond3.html
is probably the most helpful article around on Operation Starfish. A bit more in depth than the usual I like it/I don't like it. It seems that you may be better off playing the CD32 version so you can use the extra buttons.
