Your philosophy about this gun has crystallized. If Thorn was a weapon of selfishness, then the gun you make will be one of selflessness. If it's a coordinated fireteam that saved the City from Ghaul, then the gun you make will support fireteams. The Light is about standing united in service of a hopeful future.
Defeat Guardians with Hand Cannons as a team, generate Orbs of Light for fellow Guardians, and defeat Invaders in Gambit before they have killed any of your teammates.
