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 muhammadasadmughal.blogspot.com 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.
