This pump-action shotgun is probably your best bet when your enemies are close, though the wide spread of its blast makes it pretty useless against distant enemies. You can load the weapon with up to eight shells, and you can fire them one at a time with the primary attack button. You’ll automatically give the shotgun a quick pump after each shot. Though the shotgun resembles a Franchi SPAS-12, this model has an additional bonus – the secondary attack lets you fire two shots at once causing a devastating amount of damage. (This weapon is not a double-barrelled shotgun – the tube underneath the barrel simply holds the ammunition. The secondary attack simply fires two shots from the same barrel in very rapid succession.)

Using the shotgun can be tricky at times – as well as having a limited range, the shotgun can only be reloaded one shell at time. It takes several seconds to fill the weapon with all eight shells, though in an emergency you can interrupt the reloading process by simply pressing the fire button. Nevertheless, you may feel that you spend more time reloading this gun than you do firing it.

Although the standard shotgun weapon model somewhat resembles a SPAS-12, the weapon icon in the HUD is a different type of shotgun. The Half-Life High Definition pack remedies this by replacing the icon, as well as making the weapon model itself look far more like an authentic SPAS-12.
