On Narcogen's birthday, a special Gunsmith quest opened for those who have already collected four Dark Age relics and turned them in to Banshee. The reward? The heavy fusion rifle, Sleeper Simulant. This video shows each step of the process, including the missions, the public events, and the final level 280 strike.
Special thanks to CougRon, ChrisTheeCrappy, Freew1ll and Louis Wu for helping me get this great gun!
