The game features different combat styles for mech/foot units, the importance of support, air and artillery operations, an attrition-based loss system and fog of war, with significant "initiative" benefits that urge both players to keep on attacking (or else...). Players will use 560 two sided counters, representing units from regiments to companies and kampfgruppen. Students of the campaign will enjoy a highly detailed OB, drawn from both German and Soviet sources, and appreciates the realistic allowance of the very limited support of Operation Thunderclap from within the 6th Army pocket. Four scenarios are included, from a free-wheeling introductory ("We Are Coming") to the near despair of "Hoth's Last Gasp." A full campaign scenario allows players to fight through the entire 11 days that doomed the Third Reich, while a highly valid "what if" scenario allows the use of units which were assigned to the campaign but did not arrive in time, or units which were present and could have (should have?) been used. If you think you've seen it all with "panzers in the snow," check out the design innovations and "bang" you'll get from Wintergewitter... and ATO's first ever "Campaign Study," with both the complete game and a separate 56 page booklet with every article focused on the history behind the game. With over 50,000 words of text, adorned with situation maps, tables and Order of Battle diagrams by top writers and designers on Eastern Front warfare. The main historical narrative is by designer Mark Stille on the attempted counterstroke and its aftermath. Special articles by Prados, Tschanz, Heinsman, Mulholland, Webster, Grenier, and Nunez highlight armor, artillery, air forces, navies, disease, attrition, infantry weapons, politics, and propaganda to give you the inside scoop on the gears that turned the wheels of history during that fateful December of 1942. Weather, Luck, and What ifs are also included in this detailed look at one of the most desperate struggles of the 20th century, Operation Winter Storm. Better than a history book, you can read the articles and watch the action unfold before you on the game map.
