The first "Metal Slug" is just as explosively entertaining, ridiculously fun and hilariously funny the millionth time I've played thru it as it was the first. It's also just as challenging as ever. How the hell did people beat these games in the arcade? Players probably saved up eighty bucks just to get to the ending alone. There is some painfully noticable slowdown in the first and fourth stages, but that doesn't hold it back from being one of the best titles in the series. Highly recommend!
