Pump Shotgun

The Remington Model 870 pump-action shotgun deals heavy damage to an enemy or lighter damage to many at once. It holds 8 shells with 128 in reserve and can be shot without reloading all the shells. The spread of the pellets in a shell can take down multiple Infected at a time. The shotgun is extremely powerful. One person with a shotgun can usually hold off a horde of infected longer than someone using other tier 1 weapons. It reloads about 2 shells per second and fires 1 shell per second. The spread of the shotgun is large so pistols are a better choice for longer ranges, which are more accurate and less likely to hit teammates. A major disadvantage to both shotguns is that once their magazines are completely spent a new shell must be chambered, which increases the length of the reload animation, so players using them should reload as often as possible.

It can kill the Witch with one hit if shooting her in the eyes while she's not attacking, making it useful for getting the Cr0wnd achievement.

The side of the skin says "Renegade Rangemaster", which may be based on the real world Remington Wingmaster, one of the many versions of the 870, however the one in game does not look exactly like a Wingmaster.

When being attacked by swarms, it is best to do a melee attack after each shot to push back Infected while pumping and increase survivability. This does not work as well when surrounded on all sides.
