HS-10

The HS-10 is a semi-automatic, bullpup shotgun that is featured in Call of Duty: Black Ops. It is the last shotgun unlocked in multiplayer and is one of the avaliable weapons from the Mystery Box in Nazi Zombies. It's "Classified" until the player has purchased all other shotguns in that weapon's category.

Multiplayer
Unlocked after purchasing all other shotguns, it is unlocked at level 24. Despite being the last shotgun unlocked, it has a relatively small magazine size meaning reloads are constant, and combined with a moderate range, the player could spend more time reloading it than firing it. Dual Wield also substantially increases the size of the crosshairs, making it a rather poor choice of attachment.

Attachments

 * Dual Wield.

Trivia

 * The HS-10 is the first bullpup shotgun to appear in the Call of Duty series.
 * The HS-10 is also the only shotgun with Dual Wield attachment in Black Ops.
