Is Super Good Advice supposed to be a gatling gun?
The weapon absolutely does have three barrels, and they are set up in the balanced configuration that is seen in gatling guns and vulcan cannons.
However, I doesn't look like there is the rotating hardware on the weapon to feature rotating barrels.
With a weapon that can fire for a minute straight, it would make sense to have multiple barrels. In fact, all machine guns that feature a single barrel have to have that barrel changed after sustained fire. But those extra barrels are never carried on the weapon though -they're too heavy.
So what is up with SGA? I know the barrels don't spin in the game, but I am sure their presence is connected to the gun's ability to sustain heavy fire for extended periods. I can't imagine any other reason why they would be there, or why they would be configured in the gatling style.
Any one have any ideas?
[spoiler]*Edit* Maybe the barrels don't spin mechanically, but rotate nonetheless via space-magic teleportation?
If the gun can magic missed bullets back into the magazine, it can probably magically teleport the barrels in a rotating fashion... [/spoiler]
