Darkburst

The Darkburst is a Beam Combo for the Dark Beam in Metroid Prime 2: Echoes. It can make a blast of purple that looks like a portal to Dark Aether. It is way more powerful than the Dark Beam because it kills more enemies faster, but you have to obtain it, and it takes thirty of your missiles away. It also takes away a lot of your Dark Beam ammo. To use the Darkburst, you have to charge the Dark Beam and try to launch a missile at the same time. It will fire a big blast of purple.
