Chainsaw Beam

From Wikitroid, the Metroid wiki

The Chainsaw Beam is a beam from Super Metroid. It is only attainable through the exploitation of a glitch, and is a combination of the Wave, Spazer, and Plasma Beams.

As long as it's uncharged, the Chainsaw Beam seems to be surprisingly stable. However, its only effect is to destroy shot blocks or open doors immediately in front of Samus. No enemies have ever been damaged with the Chainsaw Beam, and only one example of any range has been noticed: If used in Tourian in the room after the hatchling Metroid attacks, a block near the center of the room will be hit regardless of where Samus is firing from.

Firing a charged shot or attempting to use a Charged Chainsaw Beam and Power Bomb attack will crash the game.
