Shotgun

A pump-action shotgun that fires 4 pellets per blast.

Advantages

Disadvantages

 * Lower DPS than the Double Barreled Shotgun
 * Lower fire rate than the Pistol

Upgrades
For 6 Unlock Points, the Shotgun can be upgraded to the Autoloader (higher rate of fire) or the Slugshot (greater range).

Trivia

 * Swapping weapons immediately after firing the Shotgun pauses the cocking animation rather than canceling it. Switching back to the shotgun will continue the animation where it left off.
 * Zombies spawn around the player when the Player picks up the shotgun. Pump-action shotguns are commonly associated with fighting zombies in popular culture. This likely began with 1978's Dawn of the Dead, whose protagonist used a 12-gauge riot gun due to his career as a SWAT officer.
