The Quadbarrel has been modified from the Masterkey to take 12 gauge shells instead, allowing you to fire 8 rounds in quick succession due to its high rate of fire. This gives the Quadbarrel the highest theoretical DPS in the game.
However, it shares most of the Sawed-Off's disadvantages such as its tiny range (20m), high spread and high durability loss.
Advantages:[]
High damage.
Fast reload speed.
High fire rate.
Small inventory size makes it suitable for storage and as a secondary weapon.
The Quadbarrel is the second weapon to be a modified version of another weapon. The weapon it's made from also has another modified version, the classic Sawed-Off.
Unlike the shotguns in Unturned Classic, the player loads 12 Gauge Shells as if it were a magazine.
