Metal slug X, the game is just pure class, oozes quality and is closely followed by the first.

Its always the same though, the first defines the series, the sequel tweaks it and adds what should have been in the first. After that further sequels are always going to struggle. How do you improve what you did before without changing the game completely?

Out of curiosity does anyone have a clue to when 4 and 5 are going to be added to mame? I would play them in the arcades but have never seen one anywhere
