Metal Slug 1,2,3,4,5,6,X

Metal Slug Anthology (called Metal Slug Complete (メタルスラッグコンプリート^?) in Japan) is a video game compilation for the PlayStation 2, PlayStation Portable and theWii. 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 theSNES era.

The graphics are exactly the same as the original versions released on arcade (and the more recent titles published on PS2 and Xbox). 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.

A downloadable version was made available on the PlayStation Store for PSP on 

Metal Slug 1-6 and X are included in the release, and the games have not been altered in any way. This is the same with the characters and abilities, which have all been kept the same. However, the game's manual erroneously states that the 'slide' ability is achievable in Metal Slug 4, 5, and 6 — Metal Slug 4 and 6 does not include this feature in either the arcade or console version.
