Only if you're lucky could you get it done in 3 runs. There are 3 activities, Throwing balls at tanks, Shooting shields with cannons and then killing Servitors and standing in the rings. You only get 2 of them per run! I'm on run 12 and I've seen the Cannons 3 times. 2 times I managed to get a Cannon, after ignoring the enemies spawning in and camping by the door for a Captain to appear. The 3rd time, a Guardian waited until I killed the captain and stole the Cannon! With the Balls at tanks toss, I got blown up 2 times when I chased a Ball near a Tank and a Guardian blew it up and me with it. Really great team Experience here, isn't it? And your defending Bungle on this? Really? So unless your wrong about what Triumph you think your completing this in (as have been other people), your really luck and I'd go out and buy several lottery tickets tonight.

That’s asking too much from them. They need the challenge done RIGHT NOW and if that can’t happen for them, Bungie made it too hard! It’s getting to be ridiculous.
