Unlockable Extras
The manual is out-dated for the PS2 version of Metal Slug Anthology. You can unlock all the art galleries by playing on any difficulty (except #6, which requires that games Hard / Extended play mode). Simply complete all the games for the gallery. Freeplay in the global options affects all games (including #6).
