Like It Never Snows did for Operation Market Garden, Day of Days takes on the the first 10 days of the Normandy landings at the company level. The Allied objectives are to land successfully and push far enough off the beaches to guarantee a rapid advance into France. The Axis player needs to either defeat the initial landings or plug them up to create a stalemate.

This game is both massive and extremely playable, giving players a unique appreciation for the issues involved at the beginning of the invasion. The importance of the initial air-drops, the real potential for brutal German counterattacks, and the need to get off the beaches quickly, all these come into sharp focus within the clean and fast-playing framework of the Standard Combat Series. Players can tackle the US landings separately as single-map scenarios, the Commonwealth landings on two maps, and of course there is the Whole Enchilada.
