Xbox Evolved is reporting that both Halo 2 and Halo 3: ODST may be released
on Games on Demand later this year, with the downloadable ODST possibly $20
less than retail price.

I don't know if this is the best place to moan about my faulty game but I
can't find anywhere else to state my grievences without paying £46 for
support which is more than double the product price. I thought I could get
support free but I keep getting directed to the billing page ...
