From their announcement:
World at War: Back of Beyond is the Battlefield Evolution: World at War supplement covering the Interwar period armies of Central Asia. The book includes new traits (Grenades, Weak AA) to give you the “interwar feel” and covers all the traits you need to play with the units of this book.
The following army lists are in this book:
• The Army of British India
• The Basmachi
• The Bolsheviks
• The Chinese Bandits
• The Chinese Warlord Army
• The Czech Legion
• The Japanese
• The Mad Baron’s Army
• The Mongolian Tribes
• The Tibetans
• The White Russians
Stats for the many vehicles such as Rolls-Royce Armoured Car, Lancaster 4×2 Armoured Car, Austin Armoured Car, Austin-Putilov Armoured Car, Austin-Kégresse Halftrack, Medium Mark C Tank, Vickers Medium Mk I Tank, Renault FT-17, Vickers Medium Mk II, Mk III and A1E1 Independent Tank are also included.
The “Larger than life Characters and eccentric Equipment” section introduces special characters for all the army lists to give you even more options. Beware – some of these characters are indeed larger than life, they extend the game into a pulpier setting, away from the historical one. You are getting rules to field an Aristocratic Adventurer, the Arms Dealer, the Artillery Officer, a retired Big Game Hunter, a Communist Demagogue, a European Spy, the Female Adventurer and Scholar, the Foreign Bodyguard and Mortar Supplier, German Mercenaries, the Heroic Scout, the Independent Journalist, Mongol Princess and Shaman, a Pilot Ace and even the Tibetan Lama with a Yeti!
All units in this book are designed by the same principles as the existing vehicles in the Battlefield Evolution: World at War rulebook and Battlefield Evolution: Pacific War Supplement also written by Agis Neugebauer.
This book requires the use of Battlefield Evolution: World at War, available from Mongoose Publishing.
