Bad Business (Sweet Business's long lost older brother in the Heavy Slot)
Exotic Heavy Machine Gun
Perk: Gatling Gun
The gun is mounted on a stationary turret and then spins up to deal massive damage with high caliber bullets.
Trait: The Whole 9 Yards
This weapon's ammo is belt-fed directly into the chambers. Equipping this weapon decreases mobility by 2 but increases resilience by 2.
RPM: 1000
Reload/Magazine: N/A
Lots of range and average stability
I thought of this in the shower, and I thought it was the best Exotic concept I've come up with in a while (possibly ever). Making it stationary is a huge drawback, but it's sheer damage and awesomeness should justify that cost.
Please Bungie, give us Sweet Business's older brother in Gatling Gun form. This would be the most Titan exotic ever made.
