To do: Document additional unused content from here.

Metal Slug Advance is the third handheld Metal Slug entry featuring a life bar and a unique collectible card system which gives weapon and player upgrades and opens up new areas within missions for extra replay value.

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 Leftovers

There's a few textual remains of a debug mode, 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.

Unused Text

In every version, at 0x797B0, is text for what looks to be a country selection, yet remains unused.

Regional Differences
