Winchester Super X3

The Winchester Super X3 is a shotgun in No More Room In Hell capable of outputting massive amounts of damage within seconds. Arguably one of, if not the best shotguns. It holds a magazine of 5+1 shotgun shells, and unlike all other shotguns, is semi-automatic, meaning no pump action is required between firing shells

Most players consider this shotgun to be a direct upgrade to the Mossberg 500a, and this is situationally true. However, it is easier to expend ammunition unreasonably using this weapon. For newer players playing longer missions, it's generally advisable that they receive a Mossberg 500a instead, as it's more sustainable.

Overview
Pros: Cons:
 * Only Semi-Automatic shotgun, capable of clearing rooms in seconds
 * Great for dealing with large clusters of Zombies
 * Quicker reload speed, compared to Remington 870
 * Rare spawn
 * High fire rate means ammo is likely to be expended in an unsustainable manner
 * Longer reload when compared to the similar Mossberg 500a
 * Holds less shells than Remington 870
 * Frequent ammo spawns of shells mean it's likely ammo will have to be split

Other
Winchester’s Super X3, or SX3, is a gas-operated semiautomatic shotgun built by FN in Belgium using what the company calls “Active Valve” technology. The Active Valve system automatically self-adjusts the gas pressure necessary to fire whatever load is thrown into the chamber. For instance, when firing the heaviest magnum loads in 3 1/2″ models, gases vent both upward and forward out of ports in the forearm, also regulating bolt speed.
