Missing Areas

An enormous thank you to 이지우 (Lee Jiwoo) for diligently researching Metal Slug 7, first finding unused stages through memory address editing, before unearthing the debug menu itself. See the Debug Menu page on how to access it, or read below for the old method (which can access one notable stage the level select can't). Alternately, you can use these DeSmuME savestates (16.3MB, compatible with v0.9.11) helpfully provided by 이지우!

Many of the unused areas appear to be leftovers that would be finished up for Metal Slug XX, or strange experiments including underwater-like physics and a 2-player mode that the game otherwise lacks.

These stages were originally accessed using Cheat Engine's "Memory View" function on the DeSmuME emulator. The sheer wall of numbers may look terrifying, but there's only two addresses you want to fiddle with:

Changing 14565B03E (area) will instantly transition to the new area; changing 14565B03F (mission) will not take effect until a transition.
Combat School challenges may behave incorrectly if warped into, lacking their usual objectives or occasionally their gimmicks, such as the sinking snow.

n/an/aGame Over.101

FOR 1-01スクラップ シマ 1
Scrap Island 1
Identical to normal 1:1 stage.

3:5 Underground Fortress 5

A vertical passage made of junk, with paths and drops leading to the bottom. This area was made into an alternate path for Mission 1 in Metal Slug XX. This is the only unused area to have a functioning minimap and background music.

5:3 Ruins Base Inside 3

A vertical passage with a Slug Flyer at the start, though it seems you can't enter it; there are no other objects. It leads to screen 21, the downward-sloping road. XX used this for an alternate path for Mission 5 and made it lead to a new area.

5:6 Ruins Base Inside 6

A horizontal tunnel that the player enters from a gap in the ceiling. It actually has a full roster of objects and enemies; the only real oddity are the slow-moving floating motorcycles at the mid-point. You reach a dead end and go back the way you came (with new enemies and objects in the path), ending in a Slug Armor you can enter. The level has a functioning exit that leads to the boss, with your character warping in right in front of it. The backdrop for this area was reused for both alternate paths in XX.

5:7 Ruins Base Inside 7

A similar tunnel to the last area, only tinted blue (similar to its appearance in XX)... but most curiously of all, the player physics are slow and floaty as if underwater! The characters also only ever use their pistol graphics even if you're wielding a weapon. There's a Slug Flyer you can enter and a long vertical drop you can fly down, leading to leftward path and another drop, but this one will kill the player. The Slug Flyer behaves normally, but ejecting will shoot the player so high they brush the top of the screen. Some type of physics test...?

5:8 Ruins Base Inside 8

The same area was the previous screen, complete with Slug Flyer, only with regular physics and you now fly up a vertical passage; trying to go the route in the last stage will trigger an invisible wall and cause the scrolling to behave strangely. There are no other objects and no exit.

6:6 Snowy Country Stronghold 6

A blank black screen with the player piloting the Slug Gigant. Exiting to the right leads to the boss fight with Allen O'Neill.

9:D Combat School Special 4-4

A copy of the Mission 4 boss arena, only without the boss. The "GO!" icon urges you to go right, but you're locked in. There's an invisible platform on the bottom left, though. This area has a totally blank bottom screen.


Found by 이지우 and inaccessible from the debug menu, this screen has two Slug Gigants, one controlled by the player and the other immobile. There's nothing to see and nowhere to go. It has a totally blank bottom screen.

... however, warping to another area will bring that extra player with you! You can't control them, naturally, but they react to enemy attacks like you'd expect and even have the P2 icon above them when entering a screen. If they die they do not respawn, though. Without the means to test it further, it's unclear why SNK chose not to include the 2-player function, besides shilling its inclusion in Metal Slug XX.
