Warning: The following page/section contains spoilers. Please read at your own risk.
At the beginning of the game, Samus crashes into a meteor field and loses her powers after getting infected by "X-parasites". When the BSL Station gives her a Metroid Vaccine, she is cured and "given a new life." After finally landing on the BSL Station she performs tedious tasks given to her by her ship, which is later implied to be Adam, the "gruff military officer", that Samus served under when she was in the military.
Samus then has to destroy the X that threatens the universe and Samus accomplishes that by making the BSL Station crash into the nearby planet of SR388 by first defeating one of the SA-X's, then defeating the Omega Metroid that BSL had been developing. Once she defeats the Metroid, her ship swoops in and saves her from the falling station.
In Metroid Fusion it is set in a open ended world. Doors open through shooting them like previous entries. Samus can absorb x parasites witch will restore health, bomb, and missiles. Samus can grab ledges and climb them. She can also wall jump but it is relatively limited. Certain X-parasites from bosses give powers to her suit while other powers are downloaded via navigation rooms. Metroid Fusion tends to be more linear and story-driven than previous entries, cutting off sections of the space station for certain parts of the story.
Metroid Fusion is one of the games available with the 3DS Ambassador Program.
