Brief as in both speed of play and File or Case or ... Dossier. :) VERY small footprint Barbarossa game. Like Philip Sabin's classic Eastern Front, only **3** hexes from Warsaw to Moscow, although a different configuration of those. 4 2-month turns, basic hex and counter dice-resolved combat odds system. But lots of combat options including Pressed Attack, No Retreat! - isn't there a game by that name? :) - Siberian Reserve Gamble, etc. NO Zones of Control. Playing time: est. 40 minutes. Germans: 3 army groups, 1+1 infantry armies, 4 panzer groups, 2+1 panzerkorps. Romanian army group. Russians: 10 infantry fronts, 4 operational tank groups, the Siberians. +3 Russian tank factories (in Leningrad, Kharkov, and Stalingrad). So 31 pieces total. Unlike in Phil Sabin's Eastern Front, rivers and hills/mountains *are* specified. At such a small scale, the Sea of Azov had to be tortured to fit, but all the surrounding areas/hexes relate properly, so .... (It *could* be done ... sort of ... Phil! :) ) Very adaptable to fast, easy solitaire play, as obviously as problems arise for both sides. —description from designer
