Hearts of Iron 4: La Resistance is an add-on for the historical real-time strategy game. The game will introduce new opportunities for underground resistance, the use of secret agents and various espionage missions. Agents can be sent into enemy territory in order to find collaborators and provide them with everything they need to undermine the regime and prepare the ground for invading armies. Or you can use agents for counterintelligence or as double agents to read enemy messages, expose the fifth column and carry out sabotage with the help of your secret army.
The add-on requires the original version of Hearts of Iron 4.
