http://www.hokutodestiny.com/ilforum/viewtopic.php?p=72783#p72783There are several new elements to this game, For starters, the first game only covers half the manga, until the end of the Raoh Arc. This game covers everything from the Story of Raoh, also the Celestial Emperor, right up until the end of the land of Shura.
Secondly, renewed actions are now more complicated to perform. The number of playable characters, has doubled since the first game.
And finally, online options are now available, that were not in the original.
One of the main points on which we have focused this time, has been to adequately reflect the level of violence, to that of the famous original manga.
The online mode will echo the Story via the "Dream Mode", that was created for the game and did not appear in the manga, this will also be available as online Co-Op.
Additionally, there is an online versus mode. There are two demos available; the first is an introductory demo for first time players, The second is more advanced and allows you to play with one of the new characters, Falco.
I recommend you try the demo of Falco, whom is one of the strongest characters in the game. The frame rate has been increased, from 30 to 65 FPS.
One of the elements that we wanted to improve with respect to the first game was to improve the speed of some of the actions being performed by the characters, is something that has been achieved.
With respect to the action itself, all have been rebuilt so the impacts inflicted will be different from the first game.
We can confirm that there will be deals on the subject of costumes, and also that there will be additional downloadable content, but we can not give any more details for the moment.
