So instead of the minigun

I know I might be a bit late about talking about it but i think this is a good idea so it’s a machine gun that has medium armour pen it looks a bit like the pkm but it is water cooled and it has changeable fire speeds now the backpack can hold about 500 rounds and with the higher fire rate you would start moving back a bit but only a tiny back step and it would come with two interchangeable barrels because if you fire for to long the water cooling fails and the barrel begins to get hot until the gun jams and the barrel needs to get changed but that’s only with a lot of continuous fire I’ll probably photoshop a idea together but for now that’s the base idea I have
