There's a game show on Xbox Live called 1 vs 100. Friday is a special Halo edition during the Live show. It will feature Halo questions. It's free and open to Gold subscribers. Just select the show, set a reminder for Friday, and it will download it before the game starts.
For 1 vs 100 Live, you play in either the crowd, the Mob, or as the one. The one tries to beat the 100 mob members by answering the questions correctly. Mob members are eliminated if they get them wrong so the one has to get the answers right to stay in the game. As they progress and more mob members are eliminated, their prize of Microsoft Points gets higher and higher. If they beat all 100 members, they get 10,000 MS Points though I've never seen anyone win that yet. At certain points in the show, the hostess will ask the one if they want to pick the money or the mob meaning they can choose to stick around and face the mob a little longer or take what they've earned so far and run. If the one gets a question wrong and loses, the Points they'd earned up till then get split up amongst the remaining Mob members. The top 3 answerers in the crowd can also win Arcade game. You'll probably be in the crowd though since Mob members and the one are determined by their total scores.
