If you're eager to get a look at the upcoming .hack fighter .hack Versus, below there's a Japanese trailer for you. Versus is the counterpart to the .hack//Beyond The World movie, which can also be seen below. If you're just interested in the game, though, skip to 1:13.
Animations and effects are more impressive than you might expect. Weird as it might feel to see .hack in the context of a fighter, this may work very well.
Versus launches in Japan June 28 on PS3.
