GameInformer offers us a 25-minutes video preview of Certain Affinity's XBLA co-op hack'n'slash, which is to my memory the longest and most complete slice of gameplay of the title we've seen so far, with a view of the intro cinematics, character selection, the first level, a shop section and a snippet of the second level. In case you're interested in Crimson Alliance, this is a must watch.
