Hearts of Iron IV: Waking the Tiger

Japan and Third Reich got their national objective trees modified, letting them take alternative route on historical scenarios. Japan step the path of democracy, while can revolt against Hitler in a civil war by fighting under the command of field marshal August von Mackensen. Overthrowing the leader of Nazi leads to restoration of the German Empire and opens cooperation with other countries against USRR.

Along that, Hearts of Iron IV: Waking the Tiger introduced mission and decision system. Players can trigger events that unlock special projects in exchange for influence, which helps reacting to situations. Missions require fulfilling certain tasks in exchange of bonuses or preventing penalties.

Additionally, Paradox Development team modified the way of organizing military: now field marshals lead groups consisting of armies commanded by generals. National unity has been divided into one parameter that shows for a government and another that reflects for war. Divisions can collect equipment left by enemy, and soldiers send to harsh environment (e.g. deserts) slowly learn how to operate on them. Lastly, airborne battles have been improved, with the implementation of volunteer squadron and the option of asg plane squadrons to moving armies.
