Metal Slug Advance

To do: Document additional unused content from here.

"Metal Slug Advance, the greatest source of disappointment known to man."

At least it was.

Unused Sprites#

There's a lot of unused animations for the player characters, mostly the likes of reloading and idle animations that would have been used for flavor.

To do: Get more of them and document them.

Alternate firing stances while crouching. This is excised from the game, thus limiting them with only one.

An unused idle animation of Tyra checking her hair. This was reimplemented in Metal Slug Defense and Metal Slug Attack.

Unused Objects#

A fair few remnants of the scrapped underwater areas remain, like the Slug Mariner, squids, floating mines, and perhaps more.

To do: Same thing, rip them and write about them

Slug Mariner#

The Slug Mariner with all the necessary animation for being used in the game.

Squid#

Another leftover from the underwater level, this time it's a squid from Metal Slug 5. It has all the animations, including exploding in a gory fashion.

Debug Mode#

There's a debug mode present in the game, most of it nigh-identical to that of the arcade games, as well as the numerical listings of a stage select. Mission 3 has ten areas (only seven are seen in gameplay, including a cutscene) and Mission 4 has seven, meaning two areas aren't accessed. Can be accessed with the following CodeBreaker codes and pausing the game while in a mission.

Debug Region Select#

Appears to be a region select used to test each region, as well as view the ending. Text and intro screens change according. It only seems to function in the Japanese version, as the other regions simply make the game restart in an endless loop.

• Note: Reset game to view screen

Regional Differences#

The title screen in the Japanese version has the katakana text "メタルスラッグ アドバンス", which means "Metal Slug Advance".
