Complete any Campaign mission on Legendary in 12 minutes or less.

First 30 minutes, then 15, now 12. Until you make it 5 minutes there won't be much of a challenge. I'm sure you all know of the Nightfall speed run. Anyway, that's the level you want.
Can this be done in co op? I tried it on co op matchmaking but didnt get it
ReplyDeletesame... i wonder if it must be done solo. my bro and i did it co-op over live with 2 consoles. i didnt die and we got it in 11:55 on contingency but no challenge!
