To quote: We pull ourselves away from Grand Theft Auto IV long enough to record this 25th episode of the Full Moon Show. We bring you the latest info on Resistance 2 and our demo in Europe next week.
We also reveal more about our 8-player online co-op in our I Want Your Job interview with Jake Biegel. Former 1UP Network Editorial Director Dan "Shoe" Hsu joins us in the mystery guest segment, and we'll bring you the latest contest from Marcus. Plus Rolf's Rant and more!
