The T3Sl4 Prototype arrived with the August 23 Classes update. It ships with cool VFX and animations and a special effect built for eliminating multiple targets at once — the community calls it one of the most fun guns in the game. Since the August 24 balance pass its effect also applies to bosses, and it was buffed by a further 10%. Price and unlock method unverified — check in-game.
