Ambush Alley Games published Ambush Alley, a rule set focused on the difficulties of asymmetrical warfare in an urban environment, in 2007 and quickly established themselves as a growing force in modern miniature gaming. Following up on the success of their original game, Ambush Alley Games has released a number of scenario and expansion books focused on subjects as diverse as the Vietnam conflict and the US involvement in Somalia. In 2009, they released Force on Force, which brought the Ambush Alley mechanics and philosophy of play to more traditional, symmetrical conflicts. In 2009, Ambush Alley Games entered into a publishing partnership with Osprey Publishing. Osprey Publishing is the leading publisher of illustrated military history.
