Extended Grapple

How to do it

The way to extend Samus's grappling beam is press Z, then up, down, and up on the control pad, then Z again. Do this quickly, and Samus's grapple will extend to approximately 3 times its normal length. You can also home onto opponents by pressing L when you pull it out. Also, you need to press A or Z when the tip of the beam is over the enemy in order to grab your opponent.
