As a prelude to the marathon, they're running a charity auction with a chance to win a sealed copy of Halo 2 signed by an assortment of Bungie staff.
Bidding is currently running at the low, low price of £81. Which is just about the going rate for a non-signed copy of Halo 2. If this takes your fancy then hop over to their ebay auction and place your bid.
Dig deep, guys. Those kids deserve it.
