This was an incredible arcade perfect handheld port. Looked and sounded just as good as the version you would stuff ten pence pieces into.

Why only 2 stars? Because it was too slavish to the arcade original. It kept the constantly draining health bar that was in the arcade machine to keep you feeding in more money. Except in the home version you can't add extra credits so you usually die to attrition at some point if you don't do an incredibly efficient speed run avoiding incoming fire and racing for the exits.
