While the normal and Dense Charge Shots are projectile attacks, the Melee Charge Shot transforms the move into a close-quarters melee attack, and turns the blue energy ball fired from the Arm Cannon into a triangular green blast, akin to a shotgun. This means that the attack cannot be reflected or absorbed like the other Charge Shot variants. The Melee Charge Shot deals 5% damage when the blast is uncharged, and 20% fully charged. The Melee Charge Shot also charges much more quickly than a regular Charge Shot. Similar to Mewtwo's Shadow Ball, depending on the force of the blast, Samus will slide backwards.
"A point-blank Charge Shot that isn't a projectile. Charging expands its range."
Prima Official Game GuideEdit
Release a shot immediately in front of you. The longer you charge it up, the wider the attack is. Note this version can hit multiple opponents; however, it can’t reflect or absorb.
