Attention: Hearts of Iron IV: Man the Guns Expansion is an expansion of Hearts of Iron IV and you need the base game to install it. From convoy attacks in the Battle of the Atlantic to fierce carrier battles on the Pacific front, this new expansion for the Paradox strategy game introduces naval combat in the middle of World War II. A time when naval technology took a giant leap.

We will have the industrial capacity to create and design our own ships, and even to use and build models of the time in great detail. The strategy acquires a new point of view thanks to the countless possibilities offered by naval battles, with German submarine herds lurking and much more.
