This party's getting crazy! Lets rock!
DMC3 SE is almoste the same as DMC3 but this one contains much more playable modes and stuff. Here you can play as Vergil (the half-demonic brother of Dante), you have a new mode "very hard" and bloody palace where you can battle for hours...
A minor point in this game is, that it doesn's contain new story or new bosses (exept Jester which you can skip 2 times and which is very annoying!). There are only 2 new cutscenes when you play with Vergil and those are the intro scenes.
You have also 2 new skins (one for Vergil and one for Dante). The new skin for Vergil is pretty cool but there for you need to beat the game on DMD then you unlock corrupted Vergil (Nelo Angelo) which you have to battle with in DMC1.
DMC3 SE is also a bit easier! Yes that's right! For the first time I managed to beat the game on normal mode without dying :p, ow yes, in the beginning of the game you can choose between 2 modes, yollow one or the gold one. Gold Mode allows you to restart from the last room when you die and the Yellow Mode lets you continue from check points regardless of how many yellow orbs you have...
So if youre a hardcore fan of DMC3 then I highly recommend this one and if you haven't played it... then go and get it right now in christ's sake! :p
