There Fut Coins wasn't much here that will surprise Fifa coins you if you've played any of the previous Metal Slugs on the numerous platforms they've appeared on. You're still running to the right, shooting everything that moves with increasingly more powerful weapons, and rescuing as many prisoners of war as you can (which are now tallied by name in a score screen on the main menu). There's a new arcing electricity gun, but otherwise, all the action we saw was straight up Metal Slug.
Metal Slug has been adapted fairly well to the DS's relatively small screen and limited power. The sprites--the same ones, for the most part, you've been seeing since the series' inception--seem to have been scaled down in size a bit, relative to the overall size of the screen, but the action was moving fast and furious without any significant slowdown. We had no trouble blasting away with the DS Lite's capable D pad and face buttons.
