About WW2: Time of Wrath
From the front lines in France and Russia to the deserts of North Africa and the airfields and convoys of Britain, the campaigns of World War II are yours to command in WW2: Time of Wrath! This turn-based grand strategy title, the highly improved and expanded sequel to WW2: Road to Victory, puts the player in charge of the political, economic and military decisions of one or more Axis or Allied nations, including minor nations. A diplomacy system based on political points allows you to sway possible allies to your side. An upgraded and expanded naval combat system includes fleet engagements, combat patrols, massive aircraft carriers, elusive raiders and U-Boats as well as a convoy system.
Concentrate precious industrial resources on building, training and upgrading a wide variety of combat units from airborne soldiers and armored divisions up to nuclear weapons! Historical leaders enhance the performance of your armies and hundreds of historical events like the Molotov-Ribbentrop Pact, Lend-Lease and more give you choices that can change the course of history. WW2: Time of Wrath is fought across turns that vary in length by season and 25 km hexes with divisions and corps, giving the player a broad strategic picture of the war while still leaving enough room for operational decisions.
