I wish I could tell you what's going on in this Dead or Alive Dimensions trailer. The video seems to detail the game's roster, as well as some of its 3DS specific features, but my limited Japanese keeps me from telling you much more. All I can say is that the game looks great, I think it has some sort of "Story" mode that interacts with other people's games (maybe through a Wi-fi tag mode?), and some guy with glowing red eyeballs shoots lasers out of his hands at Kasumi.
Don't worry though, because Kasumi has laser hands too. Good thing that whenever someone shoots lasers out of their hands, there is almost always someone else around who can also shoot lasers out of their hands, ready to cancel out the first guy's hand-lasers. If it weren't for that, I'm sure we'd have a lot more laser-hand related deaths in the world.
Oh, and if any of you know Japanese and want to help me translate this thing, that would be awesome.
