Cheats For Metal Slug Advance on the GBA

Gain Complete Achievement

• A golden level sign is a badge of honor showing the player they have completed an in-game level to the highest completion standard. It is a graphic that sits above the level select graphic. To have the golden level complete sign hang over every game level, players must collect every available item and rescue every prisoner in the level during one play through. A good tip is to use the x-ray scan card to more easily find all the prisoners and collectibles.

All Boss Cards

• The way to achieve a boss card is to destroy the boss the player is fighting as quickly as possible. If the player defeats the boss quickly, a onscreen message will pop up informing the player they succeeded in getting a boss card for that boss.

  The best way to do this is to make sure the in-game character is equipped with lots of grenades and a special weapon. On the fourth boss, use the flame shot. Try to use the Metal Slug if applicable. Players can use the Metal Slug for the second, third and final bosses.

Unlock the Extra Dungeon Mission

• During the fifth mission, collect the dungeon card. The card is located in level five, section three. In Metal Slug Advance, players can take different paths to the end of a level. To achieve the dungeon card, take the top path directly after the first playable screen of level five, section three. Then, take the top path again at the next opportunity to choose a path. This is a dead end. Kill any existing enemies at the dead end and pick up the dungeon card collectible. Head back towards the previous screen and finish the level. Once the player has completed the fifth mission and collected the dungeon card during play, exit to the mission select screen. In the upper left hand corner will be a selectable extra mission called "Dungeon."
