Looks great! I thought the game would be a real departure from the Metroid-formula but as far as I can see from this video-footage it has many similarities to ZeroMission and Prime!
I thought the game would be entirely on a grid (either moving sideways or vertically), but it seems like you can move freely (even diagonally)!
And the areas shown in this trailer look astonishing. So much verity!
I don`t know why Nintendo didn`t show any gameplay until now... especially because the release-date isn`t far away and the press already got to play it!
