Nah, I was the Voidwalker who used a Nova Bomb for him instead. Didn't have any Heavy synth that run. Thats my canon run of Crota, anyway, with my buddies. Normal, but this was before Hard was out, several of us under-level. We ALMOST get Crota down, our bearer (a titan ironically) is ALMOST there, I sling my Nova and Crota kneels...three strikes and he's DOWN. Black Hammer. BEAUTIFUL.
