Computerized War in Europe is the computer moderated simulation of the European Theater of Operations in World War Two. Players control ground, air, sea, strategic forces, production, and politics in order to change or simulate the events of World War Two. The game features brigade to corps-sized ground units, fleets of surface ships, U-Boats, Transports, and Amphibious Assault ships, and tactical and strategic airpower.

There is no "Computer" player in the game. Players make all the critical decisions including when and who to declare war on, planning the campaign strategy, and executing the sweeping movements, "blitzkriegs," bombing raids, airborne drops, and amphibious assaults.

Players can play any of a dozen scenarios and campaigns, the whole war, or create their own scenarios. There are also over 20 optional rules to modify the game and add additional detail not available in the original game.
