"Metal Slug X" is one badass game! Building upon the first game and adding a whole new level of scoring, power ups and character switching in game. This all amounts to my second favorite game in the series. The character designs, the in-jokes, the charmingly outdated but creative movie references and just the manic nature of it all speaks to my soul. This is an updated version of Metal Slug 2, which fixes the severe slowdown of the original release. However, there is still a little noticable slowdown from time to time, but not enough to care or even knock the game for it. I love this game! Like many of my favorite Neo Geo releases, it never gets old.
