Using Moprph ball bombs
If you are having trouble using the Morph ball bombs to boost yourself up try this: drop one bomb, then one second later drop another in the same spot, then the first bomb will boost you up. Then, about half-way up drop another bomb, then come back down and you will be boosted up, just in time to catch the explosion of the bomb you dropped in the air. The explosion of the floating bomb will boost you up even higher. It may take a while to get the hang of it, but keep trying.

Want to see what the heroine of Metroid Prime does when she's not hunting Metroids and Space Pirates? Don't touch your controller for a few seconds and Samus will start to relax her posture slightly, then opens a flap on her Power Blaster and fiddles with the controls.
Fire Missels 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.
