While this area is actually used being the very second screen of the game, it actually has a hidden alternate path at the end, hidden by a floor sprite. They all use the underground subway stage as their background and are devoid of enemies.

To access the debug mode, open the game in Console Mode and set debug developer mode On at the Neo Geo boot-up screen: this can be done via the Kawaks emulator, the Nebula emulator or using the Neo Geo UniBios. It is worth noting this Debug menu is shared by Metal Slug 2, X, 3, 4, and 5.
