It's in Korean and you'll have to open the link in IE for it to work.
It's the 2nd generation of Grand Chase. Similar characters but whole new look (apparently it takes place several years after the GC storyline). 3D 360 environment... with great skills/animation. If and when it comes out in English it's something to try for sure. xD Totally reminds you of SSB...
