The Zip contains: Summary of Rules with Horned Rat changes and latest FAQ corrections. Formatted to fit on to 2 or 4 sides of A4 as PDF, also DOC if you want to edit it. Based on previous summary 'Chaos in the Old World memory jogger' (CITOW_refsheet_v1.doc) by 'saxman75'. Also contains 'Horned Rat expansion Dial and Card list' spreadsheet (formerly threat_levels.xls) by 'legendgod' modified to remove typos and slightly re-formatted.
I have posted more background in the main game forums here:
