Metal Slug 3 - it's big, it's hard to the core, and it's awesome.

Unused Sound

The game's title announced out loud in a bombastic way, similar to the previous Metal Slug games. Funnily enough, the trend of silent Metal Slug title screens began with this game.

Debug Menu

おしながき

• メニューを　とじる（ＰＡＵＳＥしたまま） - Close the Menu (While Paused)
• ＳＥＴ　ＤＥＢＵＧ　ＤＩＰ
• ステージ　セレクト - Stage Select
• ＴＥＳＴ　ＳＴＡＧＥ
• サウンド　テスト - Sound Test
• リセット - Reset

It is worth noting this Debug menu is shared by Metal Slug 2, X, 3, 4, and 5.

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 NeoGeo UniBios.

Enter the game, and press COIN up twice during gameplay: after pausing, the debug menu will appear - with options to activate the debug dipswitches (which can be activated separately through other options using Kawaks) and even the ability to play on any regular level, and even some test levels not available in the actual game. There is also a Sound Test screen. Starting from this game onwards, the color test option is no longer available.

Skipping straight to areas after the kidnapping in 5: 3 1-2 will default the kidnapped character to Marco. Bizarrely, even if you rescued Marco the zombie clones will be Eri. And she also pilots the UFO at the end. On the ending, both Marco and Eri will be at the ending.

TEST STAGE

This set of bizarre test stages can also be played from the debug menu, named after the development team members.

• Andy the Wizard is an empty Mission 2, with a Metal Slug at the start of the level. The level is completely silent from music, and the level stops scrolling somewhere after the area with the Girida-Os. The SV-001 here, if destroyed with a Metal Slug Attack will spawn a new one that cycles between forward or rear-facing regular SV-001, and then the Type-R, back and forth.
• たぐち is the area if you take the upper path in Mission 1, with the barrels of flying piranhas. Scrolling is absent here and the only object available is a Rebel Armour. The level is silent again and you parachute in, instead of dropping in.
• にしの is the same area as FOR 2, but instead of a Rebel Armour, there’s two giant crabs there. After killing them, you can scroll right and find two more spawning from out of nowhere, and once they’re vanquished, the level stops scrolling.
• ふじさわ かんごく is the area where you rescue General Morden from the aliens' torture chamber (5: 8 1-7), but it stops scrolling before the machine he’s trapped in would be, and the only objects are those sinking Bull-Chan tanks you find in Mission 3. Weird.
• ヤマモト タイラー is the same area as FOR 2 and 3, but there’s no objects anywhere at all, you can scroll all the way to the end, and the boss music plays here.
• Mee Her appears to be the same as the area you see in FOR 5 and more, but it has the objects you find when you go there in the actual game. There are some minor differences however, like finding an ordinary prisoner instead of Uka, getting access to a Mobile Satellite, and finding Satiko Suzuki (the girl from Metal Slug's ending), near the prisoner. Level is completely silent (again) and when you reach the end, you will restart the area again.
• ありた ひみつこうじょう is exactly the same as the warehouse area in Mission 3 (3: 3 1-3). If you reach the end you will restart the test area.
• なかつか まよなか の ほうこう is simply an empty Mission 2.
• ぎりだ is Mission 2 again, but now has a Slug Flyer, a Metal Slug which behaves like a Type-R, and a Type-R Metal Slug to choose from at the beginning. Otherwise, the level’s empty up until the area where you find the Girida-Os, where a number of them will spawn to attack you and then the level stops scrolling.
• アンミラ is the area in Mission 5 (specifically 5: B 1-A) right after you fight the Rootmars for the first time. Oddly enough the ending music plays here. Like Mee Her and FOR 7, the level loops back as you reach the end.

Sound Test

SFX and BGM test screen. Unlike the previous games, Metal Slug 3 actually has a coherent sound test menu. Exiting this screen will boot you back to the title screen.

Reset

The final option in the debug menu will reset the game.

Unused Stage

Warping to 2: 2 2-1 with the stage select debug will lead you to this one-and-only true unused stage of the game. This is similar to the first part of Mission 3 in Metal Slug, albeit looking a little evening with some girders and elevators added here and there. There are only one type of zombie here with no items, aside from the unique lifts which are only seen here and the transport pod at the top. NeoGeo Freak magazine issue 04/2000 originally shows that the entrance originally located in 2: 2 1-1 where the VIP prisoner is in the final game.

Using the pod will warp you to 2: 3 1-1, slightly past the entrance to 2: 4 3-1. With the amounts of lifts on both sides of the area, it may be used to test elevators in 3: 3 1-3. (A video can be seen right here.)
