The Type-9 Derecho is a shockwave launcher (considered to be a rocket launcher by game mechanics) manufactured by Hellstorm. A heavy support weapon, the Derecho fires a large air-blast instead of a rocket. Any enemies that come into contact with the air-blast are sent flying backwards, taking damage if they collide with an obstacle.
The Derecho is best used in confined areas and choke-points where it can use its knock-back to best effect, but a backup weapon is a necessity for fighting bosses and large enemies as the Derecho can only push back so much weight with its blast.
