ASL Winter Offensive 2015 Bonus Pack features three Pete Shelling scenario designs and two redesigned boards (labeled 10z and 17z, to honor their heritage). The new maps "freshen" and put a new spin on some of the older boards utilizing overlays specifically designed for each board. The Board 10 overlay was designed by Steve Pleva and the Board 17 was designed by Alan Findlay. Kurt Miller painted the new art.
A Bulge scenario (Poteau Party) uses 17z; a PTO scenario (Wildcat Strike) uses 10z; and an East Front scenario (Liberation Day) uses both.
