Some game series simply refuse to move on with the times. The Metal Slug series is one of them. Ever since its conception on the Neo-Geo 14 years ago, nothing has really changed. Nearly every platform known to man has been graced with its presence, but not one has seen a single new idea. Its Victor Meldrew-like stubbornness has endeared enough shooter fans over the years but not really anyone else, so don't go expecting Metal Slug XX to welcome you with open arms if you aren't one of those fans.
