If you're like me you love metroid (hence the reason for my custom metroid plush-thingy beside me), and you'll love this game. It's as engaging as Zero (probably more) and is very good when you're sitting in a car for 2 hrs. Though the storyline is alot like Alien 2 (hence the name Ridley, the giant dragon thing,from Ridley Scott), so if you like the idea of a 'ally' trying to get an alien creature money,then you'll like this.(though for me killing baby metroids makes me sick - physically)I thought it was a pretty good game for a GBA game. I only gave it 4 Fun Stars because though it was fun it had that special Metroid repetetive-ness (i.e. 'Get to your ship(again)','Go to Sec. 5(again)'), and all that stuff.(and about the zero thingy it is way better[most likely due to the new storyline])

My opinion so if you don't like it , well, I don't care.

let me clear up the story the discription is wrong samus when she is infected with X crashes her ship and is injected with METROID dna (from the super metroid )and her suit is removed and modified by GF. And her suit parts are sent to the BSL where they become SA-X which frees X into the statoin .Ironicly Metroids are X predators so samus is able to absorb them to gain lost abilities and energy but she gains a weakness to cold which leaves her venrable to samus-Xs ice beam so you have to avoid it until the showdown...

I don't play video games much, and I certainly don't review them, but I have to go out on a limb here to give Metroid Fusion some stars. I just finished the game (yeah, just...like I said, I don't play much) and it was absolutely incredible. The graphics are great and the gameplay is set up in a brilliant way to keep you entertained from start to finish. That said, I found the game nigh impossible at times, but there always is a solution to each predicament. I loved how intricate the story was, and how most of the maps ended up being puzzles. I'm going to look more into the Metroid series, because the creativity in this game was phenomenal. There's a whole host of "bad guys," tons of bosses, and weapons gallore that just get better and better. My only wish would be that I could have played around with Samus at full power a little before the credits rolled, but oh well. This game is still incredible; it is an absolute blast to play and it'll work your gray matter too. 5 stars, easily.
