After Samus's armor mysteriously grows out of her glowing heart or something, we're treated to a nonstop barrage of the fastest action the series has ever seen. In addition to that, the trailer demonstrates the quick transition between third-person and first-person perspective, as well as some 3D movement in the third-person segments. Oh, and Samus faces off against Mother Brain in the end.
