Has hit BitTorrent for anyone who doesn't have it in their local arcades, (which would be almost any of us) it's true to the metal slug series in that its basically, move right, shoot, move right, shoot, move right, shoot the boss, mission complete! The one thing that threw me off was after mission one, there was a cut scene, implying there might be a story this time? I haven't played much past that because of not having time, so I don't know if there really is a story or not, but all signs point to yes. I suggest grabbing it if you dont mind no control support so you have to use a keyboard, and you're a metal slug fan.
