Cooperative gameplay is enabled on the console versions of the game, while the PSP version has a wireless mode so that two people can play together and work as a team.Ī downloadable version was made available on the PlayStation Store for PSP on October 1, 2009. The only major change is that all games now display at a converted 480i resolution (compared to the standard 240p). The graphics are virtually the same as the original versions released on arcade (and the more recent titles published on PS2 and Xbox).

The game also marks the return of SNK Playmore as a third-party developer for a Nintendo console since the SNES era. The Wii version boasts different controller configurations, most taking advantage of the Wii Remote, with the Japanese version supporting the Classic Controller and all regional variants supporting the GameCube controller. Next to the main Arcade Mode, there is Combat School, a modified version where skills are tested.Īs a bonus, the PS2 port includes an art gallery with concept art, and a sound gallery with music, from Metal Slug 1 to 6.Metal Slug Anthology is a video game compilation for the PlayStation 2, PlayStation Portable, PC and the Wii. In the Easy mode, the fifth and final level cannot be accessed, but instead of the pistol, the default weapon is the heavy machine gun with unlimited ammo.

Two new difficulty levels have been added: Easy and Hard. When the meter maxes out, enemies drop coins. When enemies are killed at a fast rate, more points are received, and this is reflected by a meter at the bottom of the screen. An additional melee attack has been added, and the sliding technique from the previous game has been removed. Next to new drivable vehicles, there is also a new weapon, the Zantetsu Sword, a blade that neutralizes enemy firepower. 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. The characters also vary by running speed, the defense abilities when driving vehicles, and the amount of ammo received. 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.

In this version however, all sides team up to combat a threat together. 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. The seventh main game in the series stays close to the fast-paced 2D side-scrolling shooting gameplay of the original, but with a few enhancements.
