From the publisher:

ASL Winter Offensive 2012 Bonus Pack #3 is a small scenario bundle (three scenarios) with two special "double-wide" geomorphic maps which are specifically designed for use with Advanced Squad Leader.  These two maps are designed to be geomorphic on three sides, and match up to each other on one long edge providing a large village playing area.

MMP has an ulterior motive, however, for the manufacture and sales of this particular product. 60% of the sales of each WO Bonus Pack 2012 are donated to the WWII Foundation [the donation is also made for purchases from Wargame Depot]. You get a nice set of new maps and three more ASL scenarios and a great project dedicated to memorializing the efforts of the men who fought in WWII get a very nice donation. This really seems like a win/win in our opinion.

ASL Winter Offensive 2012 Bonus Pack contains:

2 ASL/ASLSK geomorphic "double-wide" mapboards (map 64 and map 65)
3 new ASL scenarios

Scenarios:

WO6 - The Heat Is On - 6 1/2 turns, board 57 and 65, 17 January 1942 Pogost'e Russia
