After the Drum Gun here is... the Drum Shotgun! It has recently been data mined in the game following the arrival of the v9.30 update.
Warning: the gameplay visible above is not the gameplay of the Drum Shotgun! The leaker simply replaced the Tactical Shotgun model with the Drum Shotgun model to show what it will look like once in game.
The presence of the "drum" probably means that this shotgun will be able to fire many times before it has to be recharged and that it can be fully recharged in a single movement rather than having to reload it one bullet after another.
On the other hand, it may be less accurate or do less damage than the other shotguns available for now.
