Metal Slug X (on Metal Slug Anthology for PS2, Wii and PSP)
W- Metal Slug X is a redo of Metal Slug 2, and I personally found it to be the better of the two. There’s a bunch of new content added in, plus the slowdown problems of MS2 have been toned down considerably. It’s also packed with more interactive environments. If you want the best Metal Slug games on the Virtual Console, choose this and MS3.
