Metroid 2 - Return Of Samus - Game cheats, tips and tricks for Gameboy Color

60 missiles and 99 health:
--------------------------
Enter your ship and run left
to right until both walls are hit once.

Hint: 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.
