The HS-10 is a shotgun available in the Call of Duty: Black Ops Nazi Zombies maps Kino der Toten, "Five", Ascension, and Call of the Dead from the Mystery Box. It has medium range, decent power and a six round magazine.
When upgraded, it becomes the "Typhoid & Mary", giving it the Dual Wield attachment and two extra rounds per magazine, totaling 16 rounds. Additionally, the entire gun is reloaded at once rather than one shell at a time. However, due to the Dual Wield attachment, accuracy is significantly decreased. The right wielded gun makes a different firing noise as well.
- In the opening cutscene of "Five", Richard Nixon is dual-wielding HS-10s.
- The name Typhoid & Mary is related to a murderer called Typhoid Mary, who killed people with Typhoid Fever.
