Operation Neptune offers 6 new Battle Maps: 4 of them are normal Battle Maps and 2 are double-sized, giant Battle Maps. New features like the “Command Posts” and the “Few Good Men” rules give these new maps a character of their own. This expansion also includes 2 new Items, 2 new Awards and 1 new Specialist, the "Executive Officer", who comes in 4 different versions (depending on the player color).

The Battle Maps are:

Mission Albany

Mission Boston
