As the milestone anniversary of Halo approaches, the wheels of charity keep turning. On July 2, TrueAchievements.com will host “The Ultrafun: Halo Forever! (For a day),” a 24-hour “Halo” marathon to raise money for Child’s Play. Here’s how it works: Two teams of four will romp through “Halo 3,” “ODST” and “Reach” on Legendary. As more people donate money, the teams will back out into the lobby and turn on progressively harder skulls (excluding Iron, which, honestly, I don’t blame them). If the team passes $50,000, they’ll keep playing for 30 hours straight. The event will be streamed live on the group’s USTREAM channel. Visit the team’s site for more information on how you can help out. Be sure to stay nourished, guys!(Hitmonchan 18:41:34 UTC)

The next wave of Bungie charity auctions is live now on eBay – another 13 items, mostly artwork, but also the Macaroni Sgt.
