Missing Areas


Metal Slug 4 offers a whopping zero unused areas or warps. Bummer. On the bright side, warping straight to the bad ending has an amusing twist.
Each screen has another set of numbers in its title, likely indicating which levels were developed first.

Huge thanks to candy76041820 for the name translations.

DEMO1 END


Metal Slug 4's test stages are not used for testing stages, but instead to house the art gallery portaits that I'm dubious are actually unlockable or not; most sites claim you unlock them by completing the game, but it's never worked for me. Choosing an option that isn't numbered / has a hostage icon will freeze the game. Without the debug menu, there appears to be no way to exit these screens.
