The first part of the game is VERY action oriented and almost has a Halo feel to it, but once you get past the first planet, it's good ole Metroid goodness... a lot more exploring and puzzle solving with standard critter fights thrown in. Hyper mode is SWEET, but I know there's more to it than just temporary One Woman Army mode. There's just gotta be a bigger downside than losing a full health tank.
I REALLY hope that future FPS games rip off MP3's control scheme. This is how it should be done!
One thing I REALLY like about this is that you start off with some of the more advanced moves you had to find in previous games like the Morph ball, ball bombs, Varia Suit and double jump. SO nice to have those right away... OH! Gone is the old bomb jump method. now you just flick the remote up and you jump... but you can still use the old method if you'd like
