The Wii version boasts different controller configurations, most taking advantage of the Wii Remote, but the Classic Controller is not supported. The game also marks the return of SNK Playmore as a third-party developer for a Nintendo console since the SNES era. The graphics are exactly the same as the original versions released on arcade. Cooperative gameplay is enabled on the console versions of the game, so that two people can play together and work as a team.

Now you can have all the 2D arcade action of Metal Slug in the palm of your hand, because Metal Slug Advance has arrived on the Game Boy Advance.

Metal Slug 6 returns to the Rebel-Martian alliance featured in Metal Slugs 2, X, and 3, but on a much broader scale. Rather than repeating the previous games' events of the Martians breaking the alliance and the Rebels assisting the player in turn, the player now teams up with the Rebels and Martians to combat an even greater threat. Metal Slug 6 introduces a new play mechanic dubbed the 'Weapon Stock System'. Two gun power-ups can now be carried at the same time. Players can switch between the two weapons, or simply put them both away in favor of the default weapon. When obtaining a new weapon power-up, it will automatically occupy the inactive slot, or, if both are holstered, replace the less recent weapon of the two. The score is now multiplied by powers of 2. The faster the speed at which enemies are killed, the higher the power, as a meter at the bottom of the screen shows. When it says "Max" enemies and destructible objects will drop coins for an extra high score.

Together once more, the quartet investigate the shrouded objective of the Ptolemaic Army.

Additionally, there are new items and characters, creating a fresh new take on the Metal Slug universe.

The game takes place in the year 2030, two years after the first Metal Slug game.
