Most Memoir '44 expansion have come in one of two formats: a large white envelope with a paper map sheet and attached small set of vehicles or a small box with rules and extra figures/tiles. Most of the recent ones have been of the former type, so it was a pleasant suprise to see that the next Memoir '44 expansion will be of the meatier second style. In this case it's also suable with the regular sized maps AND with the larger Breakthrough Maps.
The main feature, besides scenarios, are a new set of Command Cards specificaly designed for use with the deeper Breakthrough Maps. I haven't had chance to try one of those yet, but it's high on my to-do list.
