My first impressions:

Nero is a coolest character ever, i would even say cooler then dante in some aspects. Blue rose, red queen and his right hand make a very good combination . I managed to stay in air and kill monsters for a minute for sure. Dante who?

Then i got to play dante and the first thing i noticed is that now he can change styles during mission and that gives him a large arsenal of moves. But even with that improvement and improved gunslinger style (now you can raise your style level by shooting) i thought that nero has more power in him. Then first i got gilgamesh and i kicked ass, then i got pandora and my face was three meters wide, then i got lucifer and the party started. Men, when you combine all devil arms and guns you get a massive blast in your brain from the amount of combinations and kick ass action and you simply can't stop to play . I'm one missions from the end and i'm looking forward to bloody palace to test who's stronger and who's better.

Got my first S on mission 19 with nero. He rocks!
