This is a reprint of the ASL Expansion titled Guerra Civil. Despite what the publisher says below, remastered really just means new artwork on the counters and scenarios. Otherwise they are pretty much the same.
From the publisher:
Years have gone by with requests coming in for a reprinting of GUERRA CIVIL, the Spanish Civil War historical module—you have been heard. But the request for a reprint has to be rejected. Instead, a fully remastered product, with all new counters. new geomorphic boards, scenarios laid out with the new format and art, not to mention all new color military art adorning the die-cut counters. Plus some extra scenarios and re-written Special Rules and notes pages. It comes to you during November 2011 as CONDOR LEGIONS and is sure to be evocative of this important time in pre World War II military history.
