Yeah I might have to do that, I was hoping for a blood angel vs tau one cause those are the armies we play. I check that one out though! thanks!
I think you would definitely have to make your own up then. Storm of Vengeance had something like 9 linked battles, some of them being optional and basically broken into 2 parts (vs Ghazkul's forces and vs Nazdreg's forces). Most of the WFB campaign packs were 4 linked battles with the results of the first three battles generally punishing the 'Home' team by denying or limiting army list choices if the 'Home' team lost.
You could do something similar using the missions in the BRB and/or Battle Missions. Battle Missions has some nifty scenarios in it that can represent final stands, breakthroughs etc. You could even throw in Planet Strike, Cityfight and Apocolypse games at various appropriate points.
With all the different options available, a flow chart style campaign over 4-5 rounds might be the most fun, with the result of a game dictating what mission the next game uses and culminating in either a final stand from the Blood Angels or a fighting withdrawal from the Tau or a couple of big, decisive battle options if the results are more even. Overall campaign results are determined by the result of that final battle and which battle the final battle ends up being (Major BA/minor BA/draw/minor Tau/Major Tau etc.). That's pretty much how the one on 216(?) went.
