Fire missiles faster
With the first gun equipped, rapidly press Y + A. As soon as the missile fires, the gun will switch back to beam weapon mode, but when you press Y again, it fires another missile. This can take down enemies in a shorter time, preventing them from having more attacks on you.
Get unreachable power-ups
If energy or ammunition is out of your reach, aim and charge your beam. The energy or ammunition will come to you.
Shoot any beam weapon repeatedly for about thirty seconds. When you stop, a heat wave can be seen in front of the arm cannon.
To acquire the Phazon Suit, you must defeat the Omega Pirate. The Phazon Suit makes you immune to most forms of Phazon radiation. It also comes equipped with the Phazon Beam, which can only be activated during the last Boss fight.
See Samus’ reaction
To see Samus’ reaction within the helmet inside of the reflection, charge and shoot directly at the ground. Note: Try this in an icy place.
Kill birds in Chozo Ruins
When you enter the Chozo Ruins, aim your gun skywards. You will see birds flying. Shoot the birds and they will explode, with feathers all over the place.
Normal Metroids (not Prime) can be dispatched rapidly by using Freeze Beam followed by a missile.
Defeating Chozo Ghosts easily
Shoot two Super Missiles to kill Chozo Ghosts. Also, if you have the X-ray Scope, you can maintain a lock on them.
The trick is to knock down the light-reflecting mirrors and bomb the plant away. At first, there is only one mirror that reflects the light and helps grow the plant. Fire at the Boss with normal fire rapidly until it is stunned; there is no need for heavy firearms. It will not be able to attack you at all if you stun it on time. After the plant Boss is stunned, run to the one reflecting mirror and shoot the red target behind the mirror with either a charge beam or only one missile. The plant will shrink and its spiky roots will vanish. Roll into a ball, go into where the roots were protecting, and drop a bomb. The plant is killed, but returns with two mirrors. Do the same thing with two mirrors, then three mirrors, then finally four mirrors. After finally killing the plant, the Varia Suit is yours.
Defeating Elite Pirates
When the Elite Pirates burst out of containment, switch to your normal beam and build up a charge shot. When the Elite is not trying to absorb energy, fire a Super Missile at them. Two Super Missiles will take them down. Use the following tactics to defeat the different kinds of Elite Pirates at the Phazon Mines. This is a very difficult area due to switching beams for certain pirates:
- Power Troopers
Use Normal Beams or charge a Normal Beam at it three to four times.
Use Wave Beams or charge a Wave Beam at it (two to four times).
Use Ice Beams or charge an Ice Beam at it and finish it with one missile.
Use the Thermal Visor to see them. Use Wave Beams or charge a Wave Beam at it at full force (two to four times); or, fire with ease with the Plasma Beam.
Fire at them with your Plasma Beam three or four times. Hide behind a wall and the Plasma Beam will end up finishing them with its burning effect. Do this to other pirates as well, even though they only need about three shots to be killed, only about one will evaporate them if you just wait patiently.
