This is the third sequel in the series and the third game to appear on DC.
There's not many changes made to the DC version. The Mercenaries, extra costumes and the Epilogue are available right from the start and they are on the main menu too.
The Mercenaries is just the same, so no changes there. When selecting New Game and you either select Hard or Easy Mode. The costume selection comes up and it looks pretty nice too. If you notice when selecting a costume, there's two new exclusive costumes to this version, which is the biggest change really - and there's no changes to the epilogue.
The DC version is alot better. Not because the Mercenaries, extra costumes and the Epilogue are available right of the bat, but it just looks nicer and it's got a little more extra detail in the backgrounds, if you look hard enough.
There's been alot of different versions of this game for other gaming systems and this is one of the best versions I've played of the game.
