The Sonic Boom is the most powerful attack in the game (save the Power Bomb and the Screw Attack ). 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 the blast reaches its target instantly, detonating on contact.
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. This attack deals large damage to both Light Aether and Dark Aether enemies and can easily hit mobile targets, making it a very versatile attack. The downsides, however, are that it puts a huge drain on Samus' resources, and it is not as damaging as the Sunburst / Darkburst would be against enemies that are weak to a particular element while resisting the other. This is especially true of most Dark Aether creatures and Darklings, which take greater damage from the Sunburst.
Sonic Boom is the Annihilator Charge Combo. It projects a wave of sonic force.
Sonic Boom costs 5 Missiles, 30 Light Ammo and 30 Dark Ammo to fire.
The Sonic Boom is most effective against multiple targets in an area.
- If used immediately after the final battle with Dark Samus starts, it will take off enough health to instantly force her into phase 2 of the battle.
- In real life, a sonic boom is the sound associated with the shock waves created by an object traveling in midair faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion.
- In the data of the Metroid Prime 2: Echoes Bonus Disc, the Sonic Boom was the name of the charged Annihilator Beam, known as Disruptor in the final game, and Imploder was the name of the Charge Combo. Unused scan data exists in the game:
- "The Imploder is the Annihilator Charge Combo. It sends a blast of entangling dark matter, which then implodes in a burst of whitehot energy.
- Samus's Notes:
- Imploder costs 10 Missiles to fire, along with Light and Dark ammo.
- The Imploder is most effective against multiple targets in an area."
