343 Industries has created spartan ops in Halo 4. This side of the game is like a story adventure mode for killing things. Every week new levels are revealed, and with it new weekly challenges as well. Follow me at facebook.com/halo4daily challenges to stay updated the best ways to complete these spartan ops daily challenges.
Spartan Ops weekly challenges 01/07 - 01/14
Creeping 'N Crawling: Kill 80 Crawlers - 1,250 XP
One of the best levels for this is the last level of the first episode. There's a part where you fight at least 20 crawlers. There are probably some better levels in the second episode too.
Watchful Avenger: Kill 20 Watchers - 1,500 XP
This one's pretty easy, it's just hard to find enough watchers. Levels in the second and third episodes might be good for this. It's hard to find a perfect level for this kind of thing.
Knightmare: Kill 30 Knights - 1,750 XP
This one's kind of tough to get, it seems like Knights are never plentiful enough. The second episode and on have the most knights. The first episode is primarily covenant. Just do a whole episode of the second episode and i'm sure you'll get this one in no time.
