Characters[]

The game has the same set of characters in Metal Slug 6 with the same abilities as its predecessor:

Marco Rossi	Marco's default weapon (Pistol on Normal and Hard, Heavy Machine Gun on Beginner) has twice the ordinary strength.
Tarma Roving	While Tarma is riding in or on a Slug, durability and the effects of power-ups are doubled; additionally, the Vulcan cannon's power is increased by 50%. He also is capable of using Vulcan Fix when on or in any vehicle.
Fiolina Germi	Fio begins each mission with the Heavy Machine Gun (on Beginner mode, she begins with the Big Heavy Machine Gun from Metal Slug X and 3). Weapon supply is also increased by 50%.
Eri Kasamoto	Eri receives twice as many grenades upon starting or resupplying. When throwing, she can aim in a specific direction.
Ralf Jones	Melee attack speed is doubled, at the expense of weapon and grenade supplies being halved. He can also use the special "Vulcan Punch" attack, melee strikes capable of damaging vehicles. Can take two hits from most attacks before losing a life.
Clark Still	Clark gets an extra chance at the start of a respawn. He can perform his "Argentina Backbreaker" against most non-vehicle enemies, and he's immune to damage during the move, also earning generous amounts of points with such action.
Leona Heidern	The new exclusive character. Leona is able to keep her weapons when she loses a life. She can perform her "Moon Slasher" attack, a circular attack capable of destroying vehicles and bullets and she carries 12 star shaped grenades instead of the usual 10.

New Features and Differences[]

PlayStation Portable[]

The screen and graphics are not re-dimensioned anymore, like in the Nintendo DS. Additionally, the player can select the aspect ratio of the screen:
- 4:3 (Regular aspect ratio with designed borders at left and right of the screen)
- Wide (Fullscreen with the graphics stretched)
- Clear (Classic Neo Geo aspect ratio)
Rebel Troops reuse their sound effects from Metal Slug 6 (except for Xbox 360/One).
Old enemies reappear again such as the Mars People and the Hunters.
Change in items, Slugs, and enemy placement. The Ostrich Slug is added in this version.
Mission 1 and Mission 6 take place in different times of day.
Infinite continues to all difficulties.
A new announcer; bits and pieces of the previous announcers can be heard.
Reintrodution of multiplayer mode by using ad hoc and online services. Unlike previous games, there is no drop-in multiplayer.
Leona Heidern as a downloadable character (costs $0.99). She has several gameplay benefits:
- Her Special Action is the Moon Slasher. It can tear down enemies and machinery with higher damage than grenades. It can also nullify projectiles.
- Vehicle Slugs' health is increased from three to four hits.
- 20% more ammo on any weapon crate.
- 20% more grenades/firebomb. Leona's grenades are her earring bombs.
- Leona keeps her weapons upon death. She loses them when continuing.
Altered challenges and ranking table in the Combat School mode. The Item Collection challenges are replaced by the returning Survival challenge and Super Devil rank. Players can switch characters without quitting back to the challenge list.
Implementation of Hidden Routes:
- Mission 1
  - Hunter Hideaway: There should be a pitfall/hole before the Di-Cokka and the DANGER barrel. Go there and fight the Hunters.
- Mission 5:
  - Deeper Ruins: When you reach the end of the second part of the stage, it says GO right. Instead, go left until you find a Warp Base. Get in the Base and fight UFOs and tons of soldiers.
  - Mars People Hallway: Just like the previous entrance but do not go in the Base. Jump over it. You should fight hordes of Mars People in there.

Xbox 360/Xbox One:[]

Trivia[]

This game, Metal Slug 6, Metal Slug 7 and Metal Slug Defense are the only game of the series to receive characters from the other franchises, whether from the company itself or from other companies.
- This makes the game, along with Samurai Shodown (2019), Art of Fighting 2 and Fatal Fury Special the only non-crossover games to receive characters from the other franchises.
