Metroid Fusion is a really fun game. For the first 2/3rds of its (quite short) runtime. The remaining 1/3rd is full of cheap and unfair situations that drain your health ridiculously quickly. Aside from this, the game takes a much more linear approach to Metroid that despite the criticism it receives actually works quite well. The powerup system is still intact as well, and works just as well as it did in the earlier games. All in all, a fun game for the most part with some glaring errors.
