Hints
Defeating Alpha Metroid
Normally, when you are in a room with an Alpha Metroid, it will not start moving until you get somewhat close to it. If you jump up and shoot it with a missile at a distance, it will appear to do nothing. However, if you then get close enough so that it starts chasing you, it will immediately take damage from the missile you shot earlier. This can be used to get some extra space at the beginning of the fight, and to kill it faster.
