Sonic Boomer

The Sonic Boomer is a custom Wonder Weapon in the non-canonical Nazi Zombies storyline Apocalypse III: Divided Destiny. The Sonic Boomer is the Thundergun equivalent. It looks exactly like it. The way the Sonic Boomer is loaded and fired is exactly the same as the Thundergun as well. However, unlike the Thundergun, the Sonic Boomer can be reloaded without having to completely empty its magazine. When Pack-a-Punched, this weapon becomes the "Sonic Explosion", obtaining a four round capacity magazine and a when fired the wind contains fire. This fire is similar to the M2 Flamethrower, as it can burn zombies to up to five seconds, increasing the player's point value. The Sonic Boomer can only achieved through the Mystery Box.
