Fusion is basically the exact opposite of Super in every single way. It's narrow and confined. It holds your hand practically the entire game and gates off exploration. It tales a straight up cinematic story (for the GBA anyway) with dialogue and cutscenes. And, most importantly, it completely reverses the role of the badass space warrior.

It should have been a catastrophic failure, but this bold experiment is easily the most distinct game in the franchise because of it. Oh, and it's pretty great. And scary. Pretty damn scary.
