Click on SS11 tab above to see the many options! This Boss Challenge is open until April 23rd. You must decide by then. The Challenge due date is May 5th - no deadline extensions! muhahahhahhaha.
Yes, I realize that this badge says Cold War and that the challenge is not about the Cold War. We all learn - Battle of the Clans is a work in progress! Just remember, we did 'Dust Bowl'...that's got to make up for a few mistakes :)
