Military Times have worked with Creative Assembly and Intel to produce a special issue about the History of the Samurai Wars.
Written by Stephen Turnbull (renown Japanese military historian and consultant for TW: Shogun 2), the magazine goes into detail about Japan during the 16th century, the historical research and battles that the game is based on.
You can read the free magazine at the link below, or pick up at places like WHSmith in the UK.
