Metal Slug First Mission is a mess, but not one that doesn’t have some redeeming qualities.
Let’s get the “working” game out of the way first. Metal Slug First and Second Mission Double Pack is kind of like Metal Slug, if Metal Slug was on a handheld, half the pack was awful, and the other half was completely missing. I have no idea what Spain looks like, but I do know what Metal Slug looks like. One of my fondest memories is going to Spain, finding a Metal Slug 2 cabinet hidden in the back corner of the bar, and pumping about one hundred quid worth of holiday money into it.
