3 A Blast from the PastLandfrog | 18/05/2007 | See all Landfrog's reviews (19)The Metal Slug games were and always will be good, graphically impressive, mindless shooters that will keep you amused for hours. Metal Slug 6 - which I believe is new to this collection - has something about it which sets it apart from the others (possibly a different graphics engine? I'm not techie enough to know for sure!).Fun as the games are, I've taken a couple of stars off for a couple of reasons.1 - The price. Surely a collection of old games should come in at around the £20 mark.2 - All the games are pretty much the same (though very good, as said before)3 - The presentation. More could have been made of the rather poor looking front-end.
