*If you die in Morphball mode, you'll see a m@$$ive explosion before Samus screams.
*If you use the Charge Beam around an energy restore, a missile restore or a power bomb restore, that item will come directly to you.
*Most enemies can be killed by just firing a charged ice beam then a missile. This is the only way to kill a Flying Pirate without it doing its self-destruct attack.
*Chozo ghosts can be defeated by a supermissile then a charged beam.
That's it... I can't think of anymore...
