Be sure to check out the malus and timing of mobilization while planning for an upcoming war. With the exception of special cases from National Focus, each mobilization step takes several weeks. Mobilization: Lack of mobilization imposes steep combat penalty on the nation.For players transitioning from vanilla to BICE, the following highlights are useful to keep in mind. The result is a game with different dynamics (and hopefully much more historical immersion and realism) than vanilla HOI4.
Game Mechanics Changes From Vanilla īlackICE overhauls the equipment system, tech trees, national focus trees, government, and combat from vanilla Hearts of Iron IV. Do not expect to win a campaign on the first try. If your only experience with HOI4 is with vanilla, you may feel as if you are playing a whole new game BICE adds and changes so many things. If you have no experience with Hearts of Iron IV, it is strongly recommended you play vanilla first to get a feel of the mechanics of the game, or BICE can be a little overwhelming. WARNING BlackICE is not for the faint hearted. As with all major overhauls ironman mode isn't recommended.
