First off.... Let me be Honest.
I am a serious metroid fan, and proud to be one of the few.
I was extremly excited to hear about the metroid series on the gamecube. Basically ,the only reason why I bought a GC was to play these games.
And I was not disappointed. This game rocks.
If you don't own a GC buy one now and get these games, they are cheap, and worth the money.
There is not much wrong with this game, it only has a few flaws and the most noticble one, is how damn hard it is. If you are not used to the GC controller, save often. Enemies will be bashing though your Chozo armour, and ripping off that little Samus bikini to ribbions in no time.
The sound, graphics are all top class, and there are references to some of the other games buried in this little GC treasure.
I'm not going to explain the storyline, the GR crew did a great job of posting the primary artice, and thus this is just one fellow gamers opinion.
Buy a GC and this game, kiss your family goodbye, and rock on, Samus!
