Sonic Boom

The Sonic Boom is the Charge Combo for the Annihilator Beam. It appears only in Metroid Prime 2: Echoes.

Description
The Sonic Boom is the most powerful attack in the game (save the Phazon Beam and Power Bomb). It uses a charged Annihilator shot, 5 Missiles and 30 Light and Dark Beam Ammo. This attack explodes as a giant wall of Light and Dark energy. Unlike the Darkburst and Sunburst, the Sonic Boom does not travel slowly. Instead it travels at super fast speeds, until it reaches a target.

The attack is unloaded from the Arm Cannon as a small cluster of sonic energy. This cluster travels very fast until reaching a target. It then erupts as a large sonic wall, that shatters and causes a ripple through reality. The surface that has been hit appears warped and cracked, as if looking through a cracked glass pane. The Sonic Boom emits translucent waves and a high pitched screeching sound, until it eventually dissipates. Any enemies to be the target of this attack take a massive amount of damage. Fast and slow enemies are both vulnerable to the Sonic Boom, making it a very versatile attack. The only downside however is the huge drain on Samus' resources.

How to obtain
The combo is comparetivley easier to acquire than the Sunburst or Darkburst. Samus must be in possession of the Annihilator Beam and the Screw Attack to obtain it. The Sonic Boom is hidden within the Ing Cache 2 in the Pirate base, Dark Agon. The Ing Cache 2 is located at the top of the Phazon Site. To get there Samus has to jump to the middle floating platform, then use her Screw Attach to reach a ledge with a Gray Door. Behind it is the Sonic Boom.
