In the build up to Microsoft's X06 event this evening we're promised a bunch of new content on Xbox Live Marketplace, the first of which happens to be a Sonic the Hedgehog demo and a trailer for IO Interactive's new action title Kane & Lynch: Dead Men.

The Sonic demo is around 315MB, making it one of the smallest demos available, so there's no excuse to not download it. More content should go live to coincide with Microsoft's X06 briefing this evening.

Carry on the conversation on the VideoGamer forums!
