really separates Metal Slug X from the rest of the crowd is its tongue-in-cheek presentation. For example, enemy soldiers laugh when you die but shriek in horror when they realize you've come back. Or when a certain midboss is defeated, his corpse falls off the screen and is devoured by a giant killer whale. This skewed sense of humor, combined with its frenzied gameplay, gives the game a unique flavor and makes it one of the best side-scrolling shooters out there". It was nominated for GameSpots annual "Best PlayStation Game" and, among console games, "Best Game No One Played" prizes. Scott Steinberg reviewed the PlayStation version of Metal Slug X for Next Generation, rating it three stars out of five, and stated that "a derivative but instantly endearing military shooter that earns its stripes". In a retrospective review, Neo-Geo.com scored Metal Slug X 10 out of 10: "Metal Slug X is different enough in many small ways that if you're a completist, you'll still want MS2 in your collection. However, if you're simply looking for the best-playing game of the two, Metal Slug X outshines its closely related cousin with a simple formula of "more, more, and more". This really is 2D action gaming at its finest".
