The game includes several special features: This is the same with the characters and abilities, which have all been kept the same, but the game's manual erroneously states that the 'slide' ability is achievable in Metal Slug 4, 5, and 6 - Metal Slug 4 and 6 do not include this feature in either the arcade or console version. Metal Slug 1- 6 and X are included in the release, and the games have not been altered in any way. Metal Slug 1- 5 and X are done via emulation of the Neo Geo AES versions, while 6 is an arcade port. It was also released on PlayStation Store for PlayStation 3 and PlayStation 4 in 20 respectively. However, this version offers less contents and an alternative menu interface. The Metal Slug Anthology was then released on PC in 2009 under the name Metal Slug Collection PC. 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.

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, PC and the Wii.
