Back again with another Reach Weekly Challenge from Bungie. This one isn't for the faint of heart either:

LIKE MIKE - 2000 cR
Finish a multiplayer matchmaking game with at least 30 kills.

So get crackin' folks. Work together or lone wolf it in Rumble Pit, either way, secure those thirty kills and you'll get a sweet 2,000 credits in return.

Also, in their most recent weekly update, Bungie announced that they will be raising their level cap when the community reaches 117 million Daily and Weekly Challenges. What does this mean? You'll have new ranks and armors available to you immediately after crossing that threshold! If that isn't incentive, I'm not sure what is!
