Just noticed this yesterday. A 2 year lasting defence of Germany campaign covering the allied strategic bombings of 1943-1945. Works on both off- & online and AFAIK doesnt require any fiddling around with the settings on the DCG, just enable and play per instructions. 3 campaign careers, medium, long & grand campaign.
