Press the special move button to charge up power, then press the special move button again to fire. Press shield or grab to stop charging, or left or right on the Control Stick to roll and stop charging as well. When the attack is fully charged, Samus' blaster will start sparkling, and one can fire a fully charged shot at any time. When used in the air, it automatically fires, either a low charged blast, or however big a shot was charged previously. A fully charged shot does 26% damage. The attack does great knockback at higher precents and is a deadly projectile for edgeguarding.
If she didn't start out with it, the Charge Shot was one of the first Power-ups Samus would get. A fully charged shot would become Samus' only way of damaging certain bosses should she run out of Missiles. In Metroid Prime a charge shot is used to clear debris blocking Samus' path. In the Metroid games the ability was called the Charge Beam.
