Gamespot got a chance to talk with Square Enix PR guy Klee Kuo about Space Invaders Extreme back at the Nintendo Media Summit, taking care to film the whole thing so that we may all watch. Included in the interview (if people talking isn't your sort of thing) is footage from both the DS and PSP versions of the game. We don't have to tell you all which one looks superior, of course.
There's also a few other trailers up of just gameplay, which we've gone ahead and embedded past the break.
