The weapon idea was completely dropped when Gearbox Software took over the development of Counter-Strike: Condition Zero.
The Pancor Jackhammer is a gas-operated 12-gauge automatic shotgun. It has a revolving magazine which 10 shots can be loaded into. Developed in 1984 by Pancor Industries, only 3 prototypes were made due to its unconventional design making it difficult to reload. However, its distinct profile has made it a frequently appearing weapon in many video games and films.
