Want to know how to get the screw attack early in Metroid Zero Mission

then watch this video
http://www.youtube.com/watch?v=qWNzrPd4gEAWhat is shown in the video is one of the many ways to get the screw attack in Metroid Zero Mission.
also In this video I fully explain (Step-by-Step) how to do this.
Things you need:
Speed Booster
Missile
Experience with running, Aiming Diagonally(R button) and Shooting(B button)I used a new intro in this video the songs are not owned by me but I thought they were cool.
I also did voice over in this video too where I explained it all Step-by-Step.

...good effort.It's not really needed until later on but this might be useful for 5% runs :)Good stuff.

Thanks
there are many ways to do this
you can do this in another area nearby too as long as your speed booster charge is on that square then this can be done
