Overview
Metal Slug 6 stays close to the fast-paced 2D side-scrolling shooting gameplay of the original Metal Slug, but with a few enhancements. The storyline is reminiscent of Metal Slug 2, X, and 3, as it focuses on the Rebel-Martian alliance where the team, with the help of the Rebels, had to fight the Martians. In this version however, all sides team up to combat a threat together. The four original heroes, Marco, Tarma, Fio and Eri, are joined by Ralf and Clark, of King of Fighters and Ikari Warriors fame, each with different attributes and a special ability. The characters also vary by running speed, the defense abilities when driving vehicles, and the amount of ammo received.
The characters can now carry two power-ups at the same time, and choose to discard one, or give it to another player in the Co-op mode. Next to new drivable vehicles, there is also a new weapon, the Zantetsu Sword, a blade that neutralizes enemy firepower. An additional melee attack has been added, and the sliding technique from the previous game has been removed.
