Oh my god! A whole new game mode. "Sparrow Demolition Derby." [spoiler]Not sanctioned by the Vanguard of course.[/spoiler]
I'm thinking the Drifter can run this under the Vanguard's nose. He seems to be good at that. But seriously, demolition derby with weaponized sparrows, Fallen or some other faction shooting at you the whole time, plus just a huge pileup mess with other guardians would be a blast. Maybe a few door prizes tossed our way for good measure.
