"Metal Slug's first foray onto the GBA is a resounding success. Even though Metal Slug Advance is a brand-new game, it has all the sights, sounds, and charm of the NeoGeo games it's based on. The addition of a card-collecting quest doesn't get in the way of the classic run-and-gun design at all. Instead, it gives players one more incentive to play through each level multiple times, as if the goofy animations and big explosions weren't already incentive enough."
