Attention digital pugilism fans everywhere: A Fight Night Round 4 demo is now available on Xbox Live Marketplace. Weighing in at 784MB and wearing the Gold Member Exclusive trunks, the demo is no featherweight either. Go grab the demo and experience the latest in blood, sweat and broken face technology. If, by chance, you happen to be stuck at work, then we suggest you add the demo to your queue and read our hands-on impressions from earlier this month.
