The last Metroid: Other M trailer confused us with its emphasis on storyline and dialogue over running and shooting. This latest trailer addresses that issue. Boy, does it ever.

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.
