Blowing enemies away is all the more fun with these shotguns.
Combat Shotgun – Left4Dead 2
Want to quickly chunk down a Tank, Witch or anything that so much as looks at you funny (teammates included)? The Combat Shotgun is the ticket. As a variant for the Auto Shotgun, the Combat Shotgun boasts a tighter spread and can use Incendiary or Explosive ammo to great effect. Range may be an issue (which can be said for many of the shotguns on this list) but its fast fire rate and 10 shell capacity are great for getting out of tight situations in a hurry.
